1 Samuel 21:1-5

Then came David to Nob to Ahimelech the priest: and Ahimelech came to meet David trembling, and said unto him, Why art thou alone, and no man with thee? And David said unto Ahimelech the priest, The king hath commanded me a business, and hath said unto me, Let no man know anything of the business whereabout I send thee, and what I have commanded thee: and I have appointed the young men to such and such a place. Now therefore what is under thy hand? give me five loaves of bread in my hand, or whatsoever there is present. And the priest answered David, and said, There is no common bread under my hand, but there is holy bread; if only the young men have kept themselves from women. And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days; when I came out, the vessels of the young men were holy, though it was but a common journey; how much more then to-day shall their vessels be holy?
