Now then, what have you at hand? Give me five loaves of bread, or whatever is here."
The priest answered David, "I have no ordinary bread at hand, only holy bread—provided that the young men have kept themselves from women."
David answered the priest, "Indeed women have been kept from us as always when I go on an expedition; the vessels of the young men are holy even when it is a common journey; how much more today will their vessels be holy?"
So the priest gave him the holy bread; for there was no bread there except the bread of the Presence, which is removed from before the Lord, to be replaced by hot bread on the day it is taken away.
