1 Samuel 21:3-4

What is under thy hand? He desires to know what he was able to do for him to supply his wants. And particularly he requests some bread for himself and servants. Or what there is present That is, any other victuals. There is hallowed bread Here in the tabernacle. Doubtless, Ahimelech had other provisions in his house; but David was in great haste, and in fear of Doeg, whom he saw and knew, and therefore would not stay till any thing could be fetched from thence. There seemed to be a double impediment to Ahimelech's giving David and his servants this bread: 1st, Its sacredness in itself, which he intimates, and in answer to which David pleads his great necessity; an answer with which Ahimelech appears to have been satisfied. “Cases of necessity, as the Jews themselves allow, often superseded the observance of the ritual laws; and this compliance of Ahimelech is urged with great force by our Saviour, in vindication of a similar infringement, Mark 2:25.” Dodd. 2d, It was requisite that all who ate of the holy bread, should have observed the same purity which was required of the priests, particularly in the instance of abstinence from all women; and Ahimelech suspected that David or his servants might possibly want this qualification, and therefore inquires concerning it. But out of respect to David he does not name him, but asks only concerning the young men. David's answer, however, shows that he was intended to be included in the inquiry.
