1 Samuel 18:6-16

6And it came to pass as they came, when David returned from the slaughter of the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet king Saul, with timbrels, with joy, and with instruments of music. 7And the women sang one to another as they played, and said,

8And Saul was very wroth, and this saying displeased him; and he said, They have ascribed unto David ten thousands, and to me they have ascribed but thousands: and what can he have more but the kingdom? 9And Saul eyed David from that day and forward.

10And it came to pass on the morrow, that an evil spirit from God came mightily upon Saul, and he prophesied in the midst of the house: and David played with his hand, as he did day by day. And Saul had his spear in his hand; 11and Saul cast the spear; for he said, I will smite David even to the wall. And David avoided out of his presence twice. 12And Saul was afraid of David, because Jehovah was with him, and was departed from Saul. 13Therefore Saul removed him from him, and made him his captain over a thousand; and he went out and came in before the people. 14And David behaved himself wisely in all his ways; and Jehovah was with him. 15And when Saul saw that he behaved himself very wisely, he stood in awe of him. 16But all Israel and Judah loved David; for he went out and came in before them.
