1st Samuel 16:20 And Saul said unto Samuel, Yea, I have obeyed the voice of the Lord, and have gone the way which the Lord sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.
[Patriarchs & Prophets pp 643] When King Saul realized that he had been rejected by God, and when he felt the force of the words of denunciation that had been addressed to him by the prophet, he was filled with bitter rebellion and despair. It was not true repentance that had bowed the proud head of the king. He had no clear perception of the offensive character of his sin, and did not arouse to the work of reforming his life.
But he brooded over what he thought was the injustice of God in depriving him of the throne of Israel and in taking the succession away from his posterity. He was ever occupied in anticipating the ruin that had been brought upon his house. He felt that the valor which he had displayed in encountering his enemies should offset his sin of disobedience. He did not accept with meekness the chastisement of God; but his haughty spirit became desperate, until he was on the verge of losing his reason.
His counselors advised him to seek for the services of a skillful musician, in the hope that the soothing notes of a sweet instrument might calm his troubled spirit. In the providence of God, David, as a skillful performer upon the harp, was brought before the king. His lofty and heaven-inspired strains had the desired effect. The brooding melancholy that had settled like a dark cloud over the mind of Saul was charmed away.
1st Samuel 16:23 And it came to pass, when the evil spirit from God was upon Saul, that David took an harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.
May The Lord add His blessing to the study of His word. God bless!
