1 Samuel 16:14–23
After the Spirit of the LORD had departed from Saul, a spirit of distress from the LORD began to torment him. / Saul’s servants said to him, “Surely a spirit of distress from God is tormenting you. / Let our lord command your servants here to seek out someone who can skillfully play the harp. Whenever the spirit of distress from God is upon you, he is to play it, and you will be well.”
1 Samuel 18:10, 11
The next day a spirit of distress sent from God came upon Saul, and he prophesied inside the house while David played the harp as usual. Now Saul was holding a spear, / and he hurled it, thinking, “I will pin David to the wall.” But David eluded him twice.
1 Samuel 19:9, 10
But as Saul was sitting in his house with his spear in his hand, a spirit of distress from the LORD came upon him. While David was playing the harp, / Saul tried to pin him to the wall with his spear. But the spear struck the wall and David eluded him, ran away, and escaped that night.
