1 Samuel 16:4-5 KJV
4 And Samuel did that which the Lord spake, and came to Bethlehem. And the elders of the town trembled at his coming, and said, Comest thou peaceably?
5 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.
