Then David came to Nob to Ahimelech the priest. And Ahimelech came to meet David trembling and said to him, “Why are you alone, and no one with you?” And David said to Ahimelech the priest, “The king has charged me with a matter and said to me, ‘Let no one know anything of the matter about which I send you, and with which I have charged you.’ I have made an appointment with the young men for such and such a place. Now then, what do you have on hand? Give me five loaves of bread, or whatever is here.” And the priest answered David, “I have no common bread on hand, but there is holy bread—if the young men have kept themselves from women.” And David answered the priest, “Truly 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 an ordinary journey. How much more today will their vessels be holy?” So the priest gave him the holy bread, for there was no bread there but 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. – 1 Samuel 21:1-6
