1 Samuel 21:6-7

6So the priest gave him holy bread; for there was no bread there but the showbread which had been taken from before the Lord, in order to put hot bread in its place on the day when it was taken away.

7Now a certain man of the servants of Saul was there that day, detained before the Lord. And his name was Doeg, an Edomite, the chief of the herdsmen who belonged to Saul.
