1 Samuel 21:3-6

Now, what food do you have with you? Give me five loaves of bread or anything you find.” The priest said to David, “I don’t have any plain bread here, but I do have some holy bread. You may eat it if your men have kept themselves from women.” David answered, “No women have been near us for days. My men always keep themselves holy, even when we do ordinary work. And this is especially true when the work is holy.” So the priest gave David the holy bread from the presence of God because there was no other. Each day the holy bread was replaced with hot bread.
