Charles Ellicott Commentary 1 Samuel 16:5

"And he said, Peaceably; I am come to sacrifice unto Jehovah: sanctify yourselves, and come with me to the sacrifice. And he sanctified Jesse and his sons, and called them to the sacrifice." — 1 Samuel 16:5 (ASV)

Peaceably: I am come to sacrifice. —The answer at once reassured the villagers. He had simply come to perform the usual rite of sacrifice among them. The reasons for his coming were unknown, but his mission was one of blessing alone. There was nothing unusual in his sanctifying Jesse and his sons. This was evidently the principal family in the place, and the village sheik and his sons would be the fittest persons to assist in preparing for, and then carrying out, the sacrificial rites.
