1 Samuel 21

1Then David came to Nob, to Ahimelech the priest. And when Ahimelech met David, he trembled and asked him, “Why are you alone? Why is no one with you?” 2“The king has given me a mission,” David replied. “He told me no one is to know about the mission or charge. And I have directed my young men to meet me at a certain place. 3Now then, what do you have on hand? Give me five loaves of bread, or whatever can be found.” 4“There is no common bread on hand,” the priest replied, “but there is some consecrated bread—provided that the young men have kept themselves from women.” 5David answered, “Women have indeed been kept from us, as is usual when I set out. And the equipment of the young men is holy, as it is even on common missions, and all the more at this time.” 6So the priest gave him the consecrated bread, since there was no bread there but the Bread of the Presence, which had been removed from before the LORD and replaced with hot bread on the day it was taken away. 7Now one of Saul’s servants was there that day, detained before the LORD. And his name was Doeg the Edomite, the chief shepherd for Saul. 8Then David asked Ahimelech, “Is there not a spear or sword on hand here? For I have brought neither my sword nor my weapons with me, because the king’s business was urgent.” 9The priest replied, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, is here; it is wrapped in a cloth behind the ephod. If you want, you may take it. For there is no other but this one.” And David said, “There is none like it; give it to me.” 10That day David fled from Saul and went to Achish king of Gath. 11But the servants of Achish said to him, “Is this not David, the king of the land? Did they not sing about him in their dances, saying: ‘Saul has slain his thousands, and David his tens of thousands’?” 12Now David took these words to heart and was very much afraid of Achish the king of Gath. 13So he changed his behavior before them and feigned madness in their hands; he scratched on the doors of the gate and let his saliva run down his beard. 14Then Achish said to his servants, “Look, you can see that the man is insane! Why have you brought him to me? 15Am I in need of madmen, that you have brought this man to rave in my presence? Must this man come into my house?”

Matthew Henry's Commentary

David with Ahimelech. (1-9) David at Gath feigns himself mad. (10-15) 1-9 David, in distress, fled to the tabernacle of God. It is great comfort in a day of trouble, that we have a God to go to, to whom we may open our cases, and from whom we may ask and expect direction. David told Ahimelech a gross untruth. What shall we say to this? The Scripture does not conceal it, and we dare not justify it; it was ill done, and proved of bad consequence; for it occasioned the death of the priests of the Lord. David thought upon it afterward with regret. David had great faith and courage, yet both failed him; he fell thus foully through fear and cowardice, and owing to the weakness of his faith. Had he trusted God aright, he would not have used such a sorry, sinful shift for his own preservation. It is written, not for us to do the like, no, not in the greatest straits, but for our warning. David asked of Ahimelech bread and a sword. Ahimelech supposed they might eat the shew-bread. The Son of David taught from it, that mercy is to be preferred to sacrifice; that ritual observances must give way to moral duties. Doeg set his foot as far within the tabernacle as David did. We little know with what hearts people come to the house of God, nor what use they will make of pretended devotion. If many come in simplicity of heart to serve their God, others come to observe their teachers and to prove accusers. Only God and the event can distinguish between a David and a Doeg, when both are in the tabernacle. 10-15 God's persecuted people have often found better usage from Philistines than from Israelites. David had reason to put confidence in Achish, yet he began to be afraid. His conduct was degrading, and discovered wavering in his faith and courage. The more simply we depend on God, and obey him, the more comfortably and surely we shall walk through this troublesome world.
