After witnesses accusing Jesus contradicted each other, Jesus said that he was the man who was also God, the Messiah, after which they decided that Jesus must die.

Mark 14:53-65

53 The men who had seized Jesus led him away to the house where the supreme priest lived. All of the Jewish Council were gathering there. 54 Peter followed Jesus at a distance. He went into the courtyard of the house where the supreme priest lived, and sat there with the men who guarded the house of the supreme priest. He was warming himself beside a fire. 55 The chief priests and all the rest of the Jewish council had already tried to find people who would tell lies about Jesus in order that they could convince the Roman authorities to execute him. But they did not succeed, 56 because, although many people spoke lies about him, they contradicted each other. 57 Finally, some stood up and accused him falsely by saying, 58 “We heard him when he said, ‘I will destroy this Temple that was built by men, and then within three days I will build another temple ◄without help from anyone else/that human hands will not build►.’” 59 But, what some of these men said also did not agree with what others of them said.

60 Then the supreme priest himself stood up in front of them and said to Jesus, “Are you not going to reply? What do you say about all the things that they are saying in order to accuse you?” 61 But Jesus was silent and did not reply [DOU]. Then the supreme priest tried again. He asked him, “Are you the Messiah? Do you say that you are ◄the Son of God/the man who is also God►?” 62 Jesus said, “I am. Furthermore, you will see me, the one who came from heaven, ruling beside God, who is completely powerful. You will also see me coming down through the clouds in the sky!” 63 In response to Jesus’ words, the supreme priest tore his outer garment. That was their custom to show that he was shocked that Jesus had said that he was equal to God. Then he said, “We certainly do not [RHQ] need any more people who will testify against this man, 64 because you have heard what he said against God! He claimed to be equal with God Therefore, what have you decided?” They all said that Jesus was guilty and deserved ◄to be executed/that they should kill him►. 65 Then some of them began spitting on Jesus. They put a blindfold on him, and then they began striking him and saying to him, “If you are a prophet, tell us who hit you!” And those who were guarding Jesus struck him with their hands.
