19 so David inquired of the Lord, "Shall I go and attack the Philistines? Will you deliver them into my hands?" The Lord answered him, "Go, for I will surely deliver the Philistines into your hands."

Matthew Henry's Commentary on 2 Samuel 5:19

Commentary on 2 Samuel 5:17-25

(Read 2 Samuel 5:17-25)

The Philistines considered not that David had the presence of God with him, which Saul had forfeited and lost. The kingdom of the Messiah, as soon as it was set up in the world, was thus attacked by the powers of darkness. The heathen raged, and the kings of the earth set themselves to oppose it; but all in vain, Acts 2:2.
