45 Then David said to the Philistine, You come to me with a sword and a spear and a javelin: but I come to you in the name of the Lord of armies, the God of the armies of Israel on which you have put shame.

Matthew Henry's Commentary on 1 Samuel 17:45

Commentary on 1 Samuel 17:40-47

(Read 1 Samuel 17:40-47)
