They wanted to kill him for being a false prophet saying he was Messiah, which all Jews will tell you only means a human descendant of David, not a God.
Then you don’t know the Bible. It is that simple:
Mark 14:
60 And the high priest stood up in the midst, and asked Jesus, saying, Answerest thou nothing? what is it which these witness against thee?
61 But he held his peace, and answered nothing. Again the high priest asked him, and said unto him, Art thou
the Christ, the Son of the Blessed?
62 And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
63 Then the high priest rent his clothes, and saith, What need we any further witnesses?
64
Ye have heard the blasphemy: what think ye? And they all condemned him to be guilty of death.
John 10:
31 Then the Jews took up stones again to stone him.
32 Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?
33 The Jews answered him, saying, For a good work we stone thee not; but for
blasphemy; and because that thou, being a man,
makest thyself God.
John 19:
7 The Jews answered him, We have a law, and by our law he ought to die, because he
made himself the Son of God.
