Bible Verses About Shewbread: Not lawful for any but the priests to eat, except in extreme cases

And the priest answered David, saying: I have no common bread at hand, but only holy bread, if the young men be clean, especially from women?

And David answered the priest, and said to him: Truly, as to what concerneth women, we have refrained ourselves from yesterday and the day before, when we came out, and the vessels of the young men were holy. Now this way is defiled, but it shall also be sanctified this day in the vessels.

The priest therefore gave him hallowed bread: for there was no bread there, but only the loaves of proposition, which had been taken away from before the face of the Lord, that hot loaves might be set up.

How he entered into the house of God, and did eat the loaves of proposition, which it was not lawful for him to eat, nor for them that were with him, but for the priests only?
