John Lightfoot on Luke 23:7

[He sent him to Herod.] Did Pilate do this as yielding to Herod a jurisdiction in capital matters within the city of Jerusalem upon those that were Galileans? Probably he did it, either in flattery to the tyrant, or else that he might throw off from himself both the trouble and the odium that might arise upon the occasion of condemning Jesus, whom he judged to be an innocent man, and whom in some measure he pitied, looking upon him as a sort of a delirant person, one not very well in his wits: which opinion also Herod seems to have conceived of him, by putting upon him that fool's coat wherewith he clothed him: which I should willingly enough render white and shining, but that I observe our evangelist, when he hath occasion to mention such a garment, calls it a white and shining robe expressly. Chapter 9:29, his garment was white and glistering: Acts 1:10, two men in white apparel.
