1 Samuel 21:3-5

3Now therefore what is under thine hand? give me five loaves of bread in mine hand, or what there is present.1

4And the priest answered David, and said, There is no common bread under mine hand, but there is hallowed bread; if the young men have kept themselves at least from women.

5And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days, since I came out, and the vessels of the young men are holy, and the bread is in a manner common, yea, though it were sanctified this day in the vessel.2
