The Tanakh clearly teaches that God Himself is the Messiah, behold:OK I'm in bed it's still dark and there's a cockerel crowing outside and maybe I'm tired and this isn't relevant but...
You do realise that literally nowhere in the Tanakh says that the moshiach will be G-d Himself and that this is an idea your religion just made up, right?
God will be the pierced(Zechariah 12:10)=Jesus is the pierced(crucifixion)
God is the only Saviour(Isaiah 43:11)=Jesus is the Saviour(Luke 2:11)
For God the way is prepared (Isaiah 40:3)=For Jesus the way is prepared (Mark 1:3 ; Matthew 3:3)
God is the Lord of Lords(Deuteronomy 10:17)=Jesus is the Lord of Lords(Revelation 19:16)
There can't be two different persons claiming this title.
God is the First (the Origin) and the Last (the goal) (Isaiah 44:6)=Jesus is the First and the Last(Revelation 1:17)
There cannot be two different persons claiming this title.
Isaiah 35:6
Say to those who have an anxious heart, Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.
