1 Samuel 21:5-6

“Definitely,” David answered the priest. “Whenever I go out to war, women are off-limits; that’s our standard operating procedure. Even on regular missions, the men’s gear is kept holy. That’s even more true today, with the mission holy along with the gear.” So the priest gave David holy bread, because there was no other bread except the bread of the presence, which is removed from the LORD’s presence and replaced by warm bread as soon as it is taken away.
