1 Samuel 16:2-3

ASV(i) 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. 3 And call Jesse to the sacrifice, and I will show thee what thou shalt do: and thou shalt anoint unto me him whom I name unto thee.
