1 Samuel 16:4-5

And Samuel did that which the LORD spake, and came to Beth-lehem. And the elders of the town trembled at his coming, and said, Comest thou peaceably? And he said, Peaceably: I am come to sacrifice unto the LORD: sanctify yourselves, and come with me to the sacrifice. And he sanctified Jesse and his sons, and called them to the sacrifice.
