What is the Biblical basis for concluding 'Jesus is Yahweh (Jehovah or LORD)'?

Christianity believes Jesus is God, or more specifically one person in God - the others being the Father and the Holy Spirit. The questions appears to accept that Jesus and God the Father are to be treated as separate persons in the Trinity, but asks for the biblical basis for concluding that Jesus is Yahweh, not the doctrinal basis for any such conclusion. In the following analysis I will refer to YHWH or Yahweh, but the English translation, Jehovah, is equally applicable.

In spite of common belief, we do not really know what the tetragrammaton, YHWH, means. It has always been written without vowel indicators and, since the Jews ceased saying the word after the Romans destroyed the Temple in 70 CE, we do not know how it was once pronounced and therefore what vowels were included in the name.

Othmar Keel and Christoph Uehlinger suggest in Gods, Goddesses, and Images of God: In Ancient Israel, page 393, Yahweh might originally have meant ‘he blows’, as a reference to his perceived original role as storm God. Lester L. Grabbe says in Ancient Israel, page 153, there is considerable – if not universal – support for the view that early Egyptian inscriptions mentioning Yhw, worshipped as a storm god in Midian, refer to the name Yhwh and that worship of Yhwh did not originate with Israel but was picked up sometime in the pre-settlement or settlement period. The Bible Study glossary agrees that ‘he blows’ has been suggested by scholars, based on etymology, along with 'He Is' and 'He Causes to Be', but, importantly in the present context, none of these has won general acceptance. The point here is not to prove that YHWH means something other than 'He Is', but that we do not know what it does mean, other than an ancient name for God.

If we can not be at all sure what YHWH meant in Old Testament usage, we can not speculate based on the assumption that in the Old Testament the name actually means 'He Is'.

Wikipedia says that Protestant commentaries often state that whenever John reports Jesus as saying ego eimi ('I am'), a claim to deity is implicit. This connection is made because it is assumed that ego eimi is related to I am that I am or Hebrew Ehyeh-Asher-Ehyeh in Exodus 3:14. A claim to deity is not at all controversial for Jesus, but this does nothing to justify a conclusion that the name Yahweh is as valid for the Son as for the Father.

Yahweh is present with the expanded name of Yeshua (Jesus), meaning "Yahweh(Ye) Saves(shua).

Isaiah 9:6 For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.

Psalm 110:1-4 The LORD said to my Lord, Sit you at my right hand,

YHWH is THE FATHER and THE WORD of YHWH is YWHW since YHWH is the one who speak.

Well the Biblical basis can be found in that Jesus often referred to himself as the 'Son of Man' which is a direct reference to the coming of the Messiah prophesied by the Prophet Daniel in the Old Testament.

There is also the matter of Jesus claiming to be able to forgive sins. This is as direct a claim at Messiahship that a first century Jews could make. The Jews knew that only God could forgive sins and it was one of the reasons that the Jewish authorities so wildly held him as a blasphemer.

Per John 1, "In the beginning was the Word and the Word was with God and the Word was God....and the Word was made flesh.

Per John 14:6, "No one comes to the Father except through me (Jesus)."

Abraham was saved by Faith as per Genesis 15:4 & 6, "And behold, the word of the LORD came to him".."And he (Abraham) believed the LORD and he counted it to him as righteousness."

Therefore LORD, Yahweh God, is all three persons of the Trinity, but when Yahweh God is speaking to man, this is done by the person and in the role of the Son of God. And this is how people who received and accepted the Word of God were saved in the Old Testament as they came to the Father through the Son (Word) of God.

Isaiah 44:6 “Thus says the Lord, the King of Israel, And his Redeemer, the Lord of hosts: ‘I am the First and I am the Last; Besides Me there is no God.

Revelation 22:13 I am the Alpha and the Omega, the Beginning and the End, the First and the Last.”

Jesus = THE first and last (true)

Yahweh = THE first and last (true)

Jesus = Yahweh (true)

(two things equal to the same thing are equal to each other, Mathematics/Logic)

In John 8:58, Jesus says to the Pharisees, "Before Abraham was, I am". He was pointedly using the same language that God himself used when speaking to Moses in Exodus 3:14, and the Pharisees understood clearly that Jesus was claiming to be God. That's why they tried to stone him for blasphemy.
