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." 12 So he sent for him and had him brought in. He was glowing with health and had a fine appearance and handsome features. Then the Lord said, "Rise and anoint him; this 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 powerfully upon David. Samuel then went to Ramah.

David Plays the Harp for Saul

14 Now the Spirit of the Lord had departed from Saul, and an evil[1] spirit from the Lord tormented him.

Matthew Henry's Commentary on 1 Samuel 16:11-14

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.
