1 Samuel 16:1-2, 6-7

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.

When they arrived, Samuel took one look at Eliab and thought, “Surely this is the LORD’s anointed!” But the LORD said to Samuel, “Don’t judge by his appearance or height, for I have rejected him. The LORD doesn’t see things the way you see them. People judge by outward appearance, but the LORD looks at the heart.”
