22 And Saul sent to Jesse, saying, Let David, I pray thee, stand before me; for he hath found favour in my sight.
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.
1 Samuel 17
1 Now the Philistines gathered together their armies to battle, and were gathered together at Shochoh, which belongeth to Judah, and pitched between Shochoh and Azekah, in Ephes-dammim.
2 And Saul and the men of Israel were gathered together, and pitched by the valley of Elah, and set the battle in array against the Philistines.
3 And the Philistines stood on a mountain on the one side, and Israel stood on a mountain on the other side: and there was a valley between them.
4 And there went out a champion out of the camp of the Philistines, named Goliath, of Gath, whose height was six cubits and a span.
5 And he had an helmet of brass upon his head, and he was armed with a coat of mail; and the weight of the coat was five thousand shekels of brass.
6 And he had greaves of brass upon his legs, and a target of brass between his shoulders.
7 And the staff of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron: and one bearing a shield went before him.
8 And he stood and cried unto the armies of Israel, and said unto them, Why are ye come out to set your battle in array? am not I a Philistine, and ye servants to Saul? choose you a man for you, and let him come down to me.
9 If he be able to fight with me, and to kill me, then will we be your servants: but if I prevail against him, and kill him, then shall ye be our servants, and serve us.
