1 Samuel 16:1-7

The LORD said to Samuel, “How long will you grieve for Saul, when I have rejected him as king over Israel? Fill your horn with oil and go; I will send you to Jesse the Bethlehemite, for I have chosen a king for Myself among his sons.” But Samuel said, “How can I go? When Saul hears about it, he will kill me.” And the LORD said, “Take a heifer from the herd with you and say, ‘I have come to sacrifice to the Lord.’ You shall invite Jesse to the sacrifice, and I will show you what you shall do [after that]; and you shall anoint for Me the one whom I designate.” So Samuel did what the LORD said, and came to Bethlehem. And the elders of the city came trembling to meet him and said, “Do you come in peace?” And he said, “In peace; I have come to sacrifice to the LORD. Consecrate yourselves and come with me to the sacrifice.” He also consecrated Jesse and his sons and invited them to the sacrifice. So it happened, when they had come, he looked at Eliab [the eldest son] and thought, “Surely the LORD’S anointed is before Him.” But the LORD said to Samuel, “Do not look at his appearance or at the height of his stature, because I have rejected him. For the LORD sees not as man sees; for man looks at the outward appearance, but the LORD looks at the heart.”
