1 Samuel 16:1-3

1The Lord said to Samuel, “How long do you intend to mourn for Saul? I have rejected him as king over Israel. Fill your horn with olive oil and go! I am sending you to Jesse in Bethlehem, for I have selected a king for myself from among his sons.”

2Samuel replied, “How can I go? Saul will hear about it and kill me!” But the Lord said, “Take a heifer with you and say, ‘I have come to sacrifice to the Lord.’

3Then invite Jesse to the sacrifice, and I will show you what you should do. You will anoint for me the one I point out to you.”
