1 Samuel 21:5-6

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.”

6So the priest gave him holy bread; for there was no bread there but the showbread which had been taken from before the Lord, in order to put hot bread in its place on the day when it was taken away.
