170. They did not know that Jesus was the Christ. So they killed Jesus..

Acts 3:15,17,

The Jews did not know that Jesus was the Christ. So they killed Jesus by nailing Him to the cross. (Lk 23:34, Act 3:15,17)

Lk 23:34 Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots.

Act 3:15 And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses. 17 And now, brethren, I wot that through ignorance ye did it, as did also your rulers.

After the resurrection of Jesus, the Jews who realized that Jesus was the Christ repented and believed in Jesus as the Christ. (Acts 2:36-38)

Acts 2:36 Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ. 37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? 38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
