As the Lord liveth. Literally, “as Jehovah liveth.” This is a remarkable statement to come from a heathen king. Some have suggested that Achish may have been attracted to the religion of the Hebrews through his association with David, as Nebuchadnezzar was led to extol the “King of heaven” through the influence of Daniel and his companions (Dan. 4:37). Others see in the oath merely an adapted substitution for what Achish actually did say. It cannot be denied that David by his behavior made a profound impression upon Achish. Thrice the king calls attention to the uprightness of David’s life (1 Sam. 29:3, 6, 9), in the one instance comparing him to “an angel of God” (1 Sam. 29:9).
