Trial before Herod (peculiar to Lk). 'By sending Jesus to Herod the clever Roman gained two ends at once. First, he got rid of the business which was imposed on him, and then he took the first step towards a reconciliation with Herod (Luke 23:12). The cause of their quarrel had probably been some conflict of jurisdiction. In that case, was not the best means of soldering up the quarrel to concede to him a right of jurisdiction within the very city of Jerusalem?'(Godet).
Luke 23:6-12
6 When Pilate heard of Galilee, he asked whether the man were a Galilaean.
7 And as soon as he knew that he belonged unto Herod's jurisdiction, he sent him to Herod, who himself also was at Jerusalem at that time.
8 And when Herod saw Jesus, he was exceeding glad: for he was desirous to see him of a long season, because he had heard many things of him; and he hoped to have seen some miracle done by him.
9 Then he questioned with him in many words; but he answered him nothing.
10 And the chief priests and scribes stood and vehemently accused him.
11 And Herod with his men of war set him at nought, and mocked him, and arrayed him in a gorgeous robe, and sent him again to Pilate.
12 And the same day Pilate and Herod were made friends together: for before they were at enmity between themselves.
