1 Samuel 16:1-2

American Standard Version

16 And Jehovah said unto Samuel, How long wilt thou mourn for Saul, seeing I have rejected him from being king over Israel? fill thy horn with oil, and go: I will send thee to Jesse the Beth-lehemite; for I have provided me a king among his sons. ² And Samuel said, How can I go? if Saul hear it, he will kill me. And Jehovah said, Take a heifer with thee, and say, I am come to sacrifice to Jehovah.
