12 So Jesse sent for him. He was dark and handsome, with beautiful eyes. And the Lord said, "This is the one; anoint him." 13 So as David stood there among his brothers, Samuel took the flask of olive oil he had brought and anointed David with the oil. And the Spirit of the Lord came powerfully upon David from that day on. Then Samuel returned to Ramah.
14 Now the Spirit of the Lord had left Saul, and the Lord sent a tormenting spirit that filled him with depression and fear. 15 Some of Saul's servants said to him, "A tormenting spirit from God is troubling you. 16 Let us find a good musician to play the harp whenever the tormenting spirit troubles you. He will play soothing music, and you will soon be well again." 17 "All right," Saul said. "Find me someone who plays well, and bring him here." 18 One of the servants said to Saul, "One of Jesse's sons from Bethlehem is a talented harp player. Not only that-he is a brave warrior, a man of war, and has good judgment. He is also a fine-looking young man, and the Lord is with him." 19 So Saul sent messengers to Jesse to say, "Send me your son David, the shepherd." 20 Jesse responded by sending David to Saul, along with a young goat, a donkey loaded with bread, and a wineskin full of wine. 21 So David went to Saul and began serving him. Saul loved David very much, and David became his armor bearer. 22 Then Saul sent word to Jesse asking, "Please let David remain in my service, for I am very pleased with him." 23 And whenever the tormenting spirit from God troubled Saul, David would play the harp. Then Saul would feel better, and the tormenting spirit would go away.

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.
Commentary on 1 Samuel 16:14-23
(Read 1 Samuel 16:14-23)
Saul is made a terror to himself. The Spirit of the Lord departed from him. If God and his grace do not rule us, sin and Satan will have possession of us. The devil, by the Divine permission, troubled and terrified Saul, by the corrupt humours of his body, and passions of his mind. He grew fretful, peevish, and discontented, and at times a madman. It is a pity that music, which may be serviceable to the good temper of the mind, should ever be abused, to support vanity and luxury, and made an occasion of drawing the heart from God and serious things. That is driving away the good Spirit, not the evil spirit. Music, diversions, company, or business, have for a time often been employed to quiet the wounded conscience; but nothing can effect a real cure but the blood of Christ, applied in faith, and the sanctifying Spirit sealing the pardon, by his holy comforts. All other plans to dispel religious melancholy are sure to add to distress, either in this world or the next.
