Charles Ellicott Commentary Luke 23:15

"no, nor yet Herod: for he sent him back unto us; and behold, nothing worthy of death hath been done by him." — Luke 23:15 (ASV)

I sent you to him.—The better manuscripts give, “he sent him back to us.”

Nothing worthy of death is done unto him.—Better, is done by Him. The translators appear to have mistaken the construction and to have taken the words as meaning “nothing worthy of death has been done to—i.e., against—Herod.” The error is common to all the English versions.
