1 Samuel 13:7-9

Now some of the Hebrews had gone over the Jordan to the land of Gad and Gilead; but as for Saul, he was yet in Gilgal, and all the people followed him trembling. And he tarried seven days, according to the set time that Samuel had appointed: but Samuel came not to Gilgal; and the people were scattered from him. And Saul said, Bring hither the burnt-offering to me, and the peace-offerings. And he offered the burnt-offering.
