3 Now therefore, what have you on hand? Give me five loaves of bread in my hand, or whatever can be found." 4 And the priest answered David and said, "There is no common bread on hand; but there is holy bread, if the young men have at least kept themselves from women." 5 Then David answered the priest, and said to him, "Truly, women have been kept from us about three days since I came out. And the vessels of the young men are holy, and the bread is in effect common, even though it was sanctified in the vessel this day." 6 So the priest gave him holy bread; for there was no bread there but the showbread which had been taken from before the Lord, in order to put hot bread in its place on the day when it was taken away.

Commentary on 1 Samuel 21:1-9
(Read 1 Samuel 21:1-9)
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.
