And David said unto Ahimelech the priest, The king has charged me with a business, and has said unto me, Let no man know any thing of the business about which I send you, and what I have commanded you: and I have directed my young men to such and such a place.
All Commentaries on 1 Samuel 21:2 Go To 1 Samuel 21

AD 435
No wonder that these dispensations were uprightly made use of in the Old Testament and that holy men sometimes lied in praiseworthy or at least in pardonable fashion, since we see that far greater things were permitted them because it was a time of beginnings. For what is there to wonder at that when the blessed David was fleeing Saul and Ahimelech the priest asked him, “Why are you alone, and no one is with you?” he replied and said, “The king gave me a commission and said, Let no one know the reason why you were sent, for I have also appointed my servants to such and such a place”? And again: “Do you have a spear or a sword at hand? For I did not bring my sword and my weapons with me because the king’s business was urgent”? Or what happened when he was brought to Achish, the king of Gath, and made believe that he was insane and raging, and “changed his countenance before them, and fell down between their hands, and dashed himself against the door of the gate, and his spittle ran down his beard”? For, after all, they lawfully enjoyed flocks of wives and concubines, and no sin was imputed to them on this account. Besides that, they also frequently spilled their enemies’ blood with their own hands, and this was held not only to be irreprehensible but even praiseworthy.
We see that, in the light of the gospel, these things have been utterly forbidden, such that none of them can be committed without very serious sin and sacrilege. Likewise we believe that no lie, in however pious a form, can be made use of by anyone in a pardonable way, to say nothing of praiseworthily, according to the words of the Lord: “Let your speech be yes, yes, no, no. Whatever is more than these is from the evil one.” The apostle also agrees with this: “Do not lie to one another.”
