“The same day there came certain of the Pharisees, saying unto him, Get thee out, and depart hence: for Herod will kill thee.”
King James Version (KJV)
13:31 Herod is minded to kill thee - Possibly they gave him the caution out of good will.
Lu 13:31 There came certain of the Pharisees. Their object was to frighten Jesus away, and hence they asserted that Herod, Herod Antipas, would kill him. He was the tetrarch of Galilee and ruler of the country beyond the Jordan, who slew John the Baptist. See PNT "Mt 2:1".
