1 Samuel 16:1-3

1The Lord said to Samuel, “How long are you going to mourn for Saul, since I have rejected him as king over Israel? Fill your horn with oil and go. I am sending you to Jesse of Bethlehem because I have selected for myself a king from his sons.”

2Samuel asked, “How can I go? Saul will hear about it and kill me!” The Lord answered, “Take a young cow with you and say, ‘I have come to sacrifice to the Lord.’

3Then invite Jesse to the sacrifice, and I will let you know what you are to do. You are to anoint for me the one I indicate to you.”
