Ok. After looking deeper into that. It is a metaphor.
Who says it is a Jewish metaphor? It is a Christian concept

The "Session of Christ" is the Christian theological doctrine that Jesus, after his ascension, is now seated at the right hand of God the Father in Heaven, signifying his permanent authority, honor, and completed work as King and Lord over the cosmos and the Church. The word "session" is an archaic term for "sitting," and the concept is found in Christian creeds, particularly the Apostles' Creed, and is described in the Bible as a position of supreme power and rule.

The Jewish people were already using it before there were Christians. 

So, you cannot show me anywhere in Acts where Peter later corrected his statement that Jesus was a man. You made a claim and you cannot prove it.
