Yes and Pilate was no Jew
Acts 4:26 The kings of the earth stood up, and the rulers were gathered together against the Lord, and against his Christ.
27 For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together,

Acts 2:23 Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
Acts 3:14 But ye denied the Holy One and the Just, and desired a murderer to be granted unto you;
15 And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.
Acts 5:30 The God of our fathers raised up Jesus, whom ye slew and hanged on a tree.
