1 Samuel 16:5-7

“Yes,” Samuel replied. “I have come to sacrifice to the LORD. Purify yourselves and come with me to the sacrifice.” Then Samuel performed the purification rite for Jesse and his sons and invited them to the sacrifice, too. 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.”
