This day will Yahweh deliver you into my hand; and I will strike you, and take your head from off you; and I will give the dead bodies of the host of the Philistines this day to the birds of the sky, and to the wild animals of the earth; that all the earth may know that there is a God in Israel,
1 Samuel 17:45-47 give the clearest expression to David’s faith in Yahweh. He viewed Yahweh as the commander of Israel’s armies, a view of God that Saul never accepted but which made the difference between Saul’s failure and David’s success as the Lord’s anointed (1 Samuel 17:45). He also saw God as the real deliverer of Israel (1 Samuel 17:46). Furthermore, David was jealous for the reputation of God (1 Samuel 17:47), not his own glory, which so preoccupied Saul. His faith must have rested on God’s promises concerning victory against the enemies of God’s people for their confidence in Him and their obedience to His word (Genesis 12:3; Deuteronomy 31:1-8; Joshua 1:1-9).
