Therefore David inquired of Yahweh, saying, Shall I go and strike these Philistines? Yahweh said to David, Go, and strike the Philistines, and save Keilah.
The writer recorded in this passage that David inquired of the Lord four times (1 Samuel 23:2; 1 Samuel 23:4; 1 Samuel 23:10-11). He placed himself under God’s authority, though Saul did not. For this reason God could and did work through David as His vice-regent. God manifested His will through the Urim and Thummim in the priestly ephod (1 Samuel 23:6; 1 Samuel 23:9; cf. Exodus 28:30). The Urim (lit. lights) and Thummim (lit. perfections) were evidently two stones or similar objects, one light and the other dark in color. The high priest carried them in the pocket on the front of his ephod (apron). He ascertained God’s will by drawing one out after mentally assigning a meaning to each. Evidently Abiathar interpreted the will of God for David.
