There shall no stranger eat of the holy thing: a sojourner of the priest, or an hired servant, shall not eat of the holy thing.
1 Samuel 21:6
So the priest gave him hallowed bread; for there was no bread there but the showbread that was taken from before the LORD, to put hot bread in the day when it was taken away.
Matthew 12:4
how he entered into the house of God and ate the showbread, which was not lawful for him to eat, neither for those who were with him, but only for the priests?
