1 Samuel 21:2-6

David answered Ahimelech the Priest, “The king sent me on a mission and gave strict orders: ‘This is top secret—not a word of this to a soul.’ I’ve arranged to meet up with my men in a certain place. Now, what’s there here to eat? Do you have five loaves of bread? Give me whatever you can scrounge up!” “I don’t have any regular bread on hand,” said the priest. “I only have holy bread. If your men have not slept with women recently, it’s yours.” David said, “None of us has touched a woman. I always do it this way when I’m on a mission: My men abstain from sex. Even when it is an ordinary mission we do that—how much more on this holy mission.” So the priest gave them the holy bread. It was the only bread he had, Bread of the Presence that had been removed from GOD’s presence and replaced by fresh bread at the same time.
