45 And David said to the Philistine, Thou comest to me with sword, and with spear, and with javelin; but I come to thee in the name of Jehovah of hosts, the God of the armies of Israel, whom thou hast defied.

Matthew Henry's Commentary on 1 Samuel 17:45

Commentary on 1 Samuel 17:40-47

(Read 1 Samuel 17:40-47)
