22 After removing Saul, he made David their king. He testified concerning him: ‘I have found David son of Jesse a man after my own heart; he will do everything I want him to do.’ (Acts 13:22)

14 But now your kingdom will not endure; the LORD has sought out a man after his own heart and appointed him leader of his people, because you have not kept the LORD’s command.” (1 Samuel 13:14)

7 But the LORD said to Samuel, “Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things man looks at. Man looks at the outward appearance, but the LORD looks at the heart.”
8 Then Jesse called Abinadab and had him pass in front of Samuel. But Samuel said, “The LORD has not chosen this one either.” 9 Jesse then had Shammah pass by, but Samuel said, “Nor has the LORD chosen this one.” 10 Jesse had seven of his sons pass before Samuel, but Samuel said to him, “The LORD has not chosen these.” 11 So he asked Jesse, “Are these all the sons you have?”
“There is still the youngest,” Jesse answered, “but he is tending the sheep.”
Samuel said, “Send for him; we will not sit down until he arrives.”
12 So he sent and had him brought in. He was ruddy, with a fine appearance and handsome features.
Then the LORD said, “Rise and anoint him; he is the one.”
13 So Samuel took the horn of oil and anointed him in the presence of his brothers, and from that day on the Spirit of the LORD came upon David in power. Samuel then went to Ramah. (1 Samuel 16:7-13)
