1 Samuel 21:3-5

3Now therefore, what have you on hand? Give me five loaves of bread in my hand, or whatever can be found.”

4And 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.”

5Then 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 consecrated in the vessel this day.”
