1 Samuel 16:1-4

Now the LORD said to Samuel, “You have mourned long enough for Saul. I have rejected him as king of Israel, so fill your flask with olive oil and go to Bethlehem. Find a man named Jesse who lives there, for I have selected one of his sons to be my king.” But Samuel asked, “How can I do that? If Saul hears about it, he will kill me.” “Take a heifer with you,” the LORD replied, “and say that you have come to make a sacrifice to the LORD. Invite Jesse to the sacrifice, and I will show you which of his sons to anoint for me.” So Samuel did as the LORD instructed. When he arrived at Bethlehem, the elders of the town came trembling to meet him. “What’s wrong?” they asked. “Do you come in peace?”
