11 And Samuel said unto Jesse, Are here all thy children? And he said, There remaineth yet the youngest, and, behold, he keepeth the sheep. And Samuel said unto Jesse, Send and fetch him: for we will not sit down  till he come hither.
11 So he asked Jesse, "Are these all the sons you have?" "There is still the youngest," Jesse answered. "He is tending the sheep." Samuel said, "Send for him; we will not sit down until he arrives."
11 Then Samuel said to Jesse, "Are all your sons here?" And he said, "There remains yet the youngest,
11 Then he asked Jesse, "Is this it? Are there no more sons?" "Well, yes, there's the runt. But he's out tending the sheep." Samuel ordered Jesse, "Go get him. We're not moving from this spot until he's here."
11 And Samuel said to Jesse, "Are all the young men here?" Then he said, "There remains yet the youngest, and there he is, keeping the sheep." And Samuel said to Jesse, "Send and bring him. For we will not sit down till he comes here."
11 Then Samuel asked, "Are these all the sons you have?" "There is still the youngest," Jesse replied. "But he's out in the fields watching the sheep and goats." "Send for him at once," Samuel said. "We will not sit down to eat until he arrives."

Commentary on 1 Samuel 16:6-13
(Read 1 Samuel 16:6-13)
It was strange that Samuel, who had been so disappointed in Saul, whose countenance and stature recommended him, should judge of another man by that rule. We can tell how men look, but God can tell what they are. He judges of men by the heart. We often form a mistaken judgment of characters; but the Lord values only the faith, fear, and love, which are planted in the heart, beyond human discernment. And God does not favour our children according to our fond partiality, but often most honours and blesses those who have been least regarded. David at length was pitched upon. He was the youngest of the sons of Jesse; his name signifies Beloved; he was a type of God's beloved Son. It should seem, David was least set by of all the sons of Jesse. But the Spirit of the Lord came upon David from that day forward. His anointing was not an empty ceremony, a Divine power went with that instituted sign; he found himself advanced in wisdom and courage, with all the qualifications of a prince, though not advanced in his outward circumstances. This would satisfy him that his election was of God. The best evidence of our being predestinated to the kingdom of glory, is, our being sealed with the Spirit of promise, and experience of a work of grace in our hearts.
