So Saul said, “Bring the burnt offering here to me, and the peace offerings.” And he offered the burnt offering.
Here is, I. Saul's offence in offering sacrifice before Samuel came. Samuel, when he anointed him, had ordered him to tarry for him seven days in Gilgal, promising that, at the end of those days, he would be sure to come to him, and both offer sacrifices for him and direct him what he should do. This we had Sa1 10:8.
Commenting on 1 Samuel 13:8-14
And Saul said,.... Being impatient, and seeing the people deserting him apace, and unwilling to engage in a battle without first sacrificing to God, and imploring his help and assistance: bring hither a burnt offering to me; that is, a creature for a burnt offering, a bullock, sheep, goat, or lamb: and peace offerings; which also were either of the herd, or of the flock...
SAUL, WEARY OF WAITING FOR SAMUEL, SACRIFICES. (Sa1 13:9-16) Saul said, Bring hither a burnt offering to me, and peace offerings--Saul, though patriotic enough in his own way, was more ambitious of gaining the glory of a triumph to himself than ascribing it to God.
