1 Samuel 21:2-3
2-3David 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!"
4"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."
