Luke 23:9

But when Pilate heard Galilee mentioned, he asked if the man was a Galilean.

When he found out that he was in Herod’s jurisdiction, he sent him to Herod, who was also in Jerusalem during those days.

Now when Herod saw Jesus, he was exceedingly glad, for he had wanted to see him for a long time, because he had heard many things about him. He hoped to see some miracle done by him.

The chief priests and the scribes stood, vehemently accusing him.

Herod with his soldiers humiliated him and mocked him. Dressing him in luxurious clothing, they sent him back to Pilate.

Herod and Pilate became friends with each other that very day, for before that they were enemies with each other.
