YHWH revealed Himself with the meaning in His name.  Stand still and see the “Yeshua of YHWH” (Salvation of the Lord).

Who forgives sins?  YHWH forgives sin, not the High Priest. YHWH is the one sitting on the Mercy Seat on the Ark of the Testimony, the High Priest makes intercession, but doesn't give the forgiveness Himself.  Did Aaron forgive Israel's sins?  No, he presented supplication before YHWH on the Day of Atonement (Yom Kippur) on behalf of the People of Israel so that their sins would be forgiven.  How do we reconcile this fact with the knowledge that Yeshua had the power to forgive sins?  And, as the gospels document, He did forgive sin.  YHWH is fulfilling the entire covenant, as YHWH, High Priest, and as the Sacrifice.  He also gives us the heart to follow the Torah.  He is healing the leper, not just declaring him whole and giving life to walking dead flesh. 

Mark 2: 6But there was certain of the scribes sitting there, and reasoning in their hearts, 7Why doth this man thus speak blasphemies? who can forgive sins but God only? 8And immediately when Jesus perceived in his spirit that they so reasoned within themselves, he said unto them, Why reason ye these things in your hearts?  9Whether is it easier to say to the sick of the palsy, Thy sins be forgiven thee; or to say, Arise, and take up thy bed, and walk? 10But that ye may know that the Son of man hath power on earth to forgive sins, (he saith to the sick of the palsy,) 11I say unto thee, Arise, and take up thy bed, and go thy way into thine house. 12And immediately he arose, took up the bed, and went forth before them all; insomuch that they were all amazed, and glorified God, saying, We never saw it on this fashion.

I find the following to be significant.

Luke 10: 21In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight.  22All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him.  23And he turned him unto his disciples, and said privately, Blessed are the eyes which see the things that ye see:  24For I tell you, that many prophets and kings have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.  

It sounds like Yeshua is saying the Father and the Son are ONE.  I don't pretend to try and explain the mechanics of Yeshua praying or being local and being omnipresent.  This is what makes these things hard to see.

The Old Testament (Tanach) is replete with YHWH clarifying there is none beside him.  What will it take for us to take Him literally?

Deuteronomy 4:35, "You were shown these things so that you might know that the LORD is God; besides him there is no other." 

 1 Kings 8:60, so that all the peoples of the earth may know that the LORD is God and that there is no other. 

 Isaiah 44:8, Do not tremble, do not be afraid. Did I not proclaim this and foretell it long ago? You are my witnesses. Is there any God besides me? No, there is no other Rock; I know not one." 

Isaiah 45:5, I am the LORD, and there is no other; apart from me there is no God. I will strengthen you, though you have not acknowledged me, 

Isaiah 45:14This is what the LORD says: "The products of Egypt and the merchandise of Cush, and those tall Sabeans— they will come over to you and will be yours; they will trudge behind you, coming over to you in chains. They will bow down before you and plead with you, saying, 'Surely God is with you, and there is no other; there is no other god.'

"Isaiah 43:11, I, even I, am the LORD; and beside me there is no saviour.

Isaiah 45:21Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.

Hosea 13:4, Yet I am the LORD thy God from the land of Egypt, and thou shalt know no god but me: for there is no saviour beside me. 

I think He is trying to tell us something.  Those scriptures that talk of Yeshua at His right hand are more accurately translated showing He IS the Right Arm of YHWH on the throne. 

 Psalm 98:1, [ A psalm. ] Sing to the LORD a new song, for he has done marvelous things; his right hand and his holy arm have worked salvation for him.

Isaiah 52:10 The LORD will lay bare his holy arm in the sight of all the nations, and all the ends of the earth will see the salvation of our God.

Isaiah talks of YHWH, the Father, and the Son as being the same person. 

 Isaiah 9:5-5For every battle of the warrior is with confused noise, and garments rolled in blood; but this shall be with burning and fuel of fire.  6For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace. 7Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this." 

This is describing ONE person, not many.  This is describing the child's name that was born.  Genesis 22 tells the story plainly.  Christianity has been reading this scripture wrong for too long. 

Genesis 22: 7And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering?  8And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.

I don't think YHWH can be any clearer.  YHWH provided Himself as the lamb for redemption of the people.

John 11:49And one of them, named Caiaphas, being the high priest that same year, said unto them, Ye know nothing at all, 50Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not. 51And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;  52And not for that nation only, but that also he should gather together in one the children of God that were scattered abroad.

John 18:13-15 13And led him away to Annas first; for he was father in law to Caiaphas, which was the high priest that same year. 14Now Caiaphas was he, which gave counsel to the Jews, that it was expedient that one man should die for the people. 15And Simon Peter followed Jesus, and so did another disciple: that disciple was known unto the high priest, and went in with Jesus into the palace of the high priest. 

Yeshua said He had another flock.  Who is the other flock?  The Kingdom that was promised to the Patriarchs was divided after Solomon's reign. Yeshua still needs to restore the kingdom.  That is one of the tasks of the Messiah.  It is central to His work.  That is why the apostles asked if it was time for the Kingdom of Israel to be restored.  The southern Kingdom/Judah has returned.  Ephraim/Northern Kingdom is still in Diaspora.  The Messiah will gather his flocks into one sheepfold.  He will join His two staves together in one stick and the Kingdom will be restored.  Joseph is symbolic of the Northern Kingdom/Ephraim in Diaspora.  He is hidden and has forgotten who he is.

So what did Peter have to say that was so profound and insightful that Yeshua declared he understood something that only YHWH could have revealed to him?

Matthew 16:13When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?  14And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.  15He saith unto them, But whom say ye that I am?  16And Simon Peter answered and said, Thou art the Christ, the Son of the living God.  17And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.  18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.  19And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.  20Then charged he his disciples that they should tell no man that he was Jesus the Christ.  21From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.

Peter understood that Yeshua is the son, the flesh and blood of the living YHWH.  And Yeshua further promised that upon this understanding He would build His house.  Then he charged His disciples not to reveal it to anyone yet, likely knowing this would result in His judgment and death. 

John 5: 17But Jesus answered them, My Father worketh hitherto, and I work.  18Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.  19Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise.

Yeshua submitted Himself to this fate knowing that His sacrifice must happen, but the sacrifice needed to occur on Passover.  Through His offering He would draw many people to Him.

John 12: 31Now is the judgment of this world: now shall the prince of this world be cast out.  32And I, if I be lifted up from the earth, will draw all men unto me.  33This he said, signifying what death he should die.

How do we then understand John 17 in the context of following the Torah and the declaration of the Shema?  The Shema is stated in Deuteronomy 6:4 and is considered the foundation stone of the Jewish faith.  Interestingly enough they are right. 

Deuteronomy 6:4Hear, O Israel: The LORD our God is one LORD:

Ephesians 2: 19Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; 20And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; 21In whom all the building fitly framed together groweth unto an holy temple in the Lord:

Isaiah 28: 15Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves: 16Therefore thus saith the Lord GOD, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner stone, a sure foundation: he that believeth shall not make haste. 17Judgment also will I lay to the line, and righteousness to the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place.

1 Peter 2: 5Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ. 6Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded. 7Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner,
