Luke 23:8-12

23:8 When Herod saw Jesus, he was very glad, for he had long desired to see him, because he had heard about him and was hoping to see him perform some miraculous sign. 23:9 So Herod questioned him at considerable length; Jesus gave him no answer. 23:10 The chief priests and the experts in the law were there, vehemently accusing him. 23:11 Even Herod with his soldiers treated him with contempt and mocked him. Then, dressing him in elegant clothes, Herod sent him back to Pilate. 23:12 That very day Herod and Pilate became friends with each other, for prior to this they had been enemies.

Luke 23:15

23:15 Neither did Herod, for he sent him back to us. Look, he has done nothing deserving death.
