1 Samuel 18 [1.] When he had finished speaking to Saul, the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul. Saul took him that day, and would let him go no more home to his father’s house. Then Jonathan and David made a covenant, because he loved him as his own soul. Jonathan stripped himself of the robe that was on him, and gave it to David, and his clothing, even including his sword, his bow, and his sash. David went out wherever Saul sent him, and behaved himself wisely; and Saul set him over the men of war. It was good in the sight of all the people, and also in the sight of Saul’s servants. As they came, when David returned from the slaughter of the Philistine, the women came out of all the cities of Israel, singing and dancing, to meet king Saul, with tambourines, with joy, and with instruments of music. The women sang to one another as they played, and said,
“Saul has slain his thousands,
David his ten thousands.”
1 Samuel 18 [8.] Saul was very angry, and this saying displeased him. He said, “They have ascribed to David ten thousands, and to me they have ascribed only thousands. What can he have more but the kingdom?” Saul watched David from that day and forward. On the next day, an evil spirit from God came mightily on Saul, and he prophesied in the middle of the house. David played with his hand, as he did day by day. Saul had his spear in his hand; and Saul threw the spear, for he said, “I will pin David even to the wall!” David escaped from his presence twice. Saul was afraid of David, because Yahweh was with him, and had departed from Saul. Therefore Saul removed him from his presence, and made him his captain over a thousand; and he went out and came in before the people.
1 Samuel 18 [14.] David behaved himself wisely in all his ways; and Yahweh was with him. When Saul saw that he behaved himself very wisely, he stood in awe of him. But all Israel and Judah loved David; for he went out and came in before them. Saul said to David, “Behold, my elder daughter Merab, I will give her to you as wife. Only be valiant for me, and fight Yahweh’s battles.” For Saul said, “Don’t let my hand be on him, but let the hand of the Philistines be on him.” David said to Saul, “Who am I, and what is my life, or my father’s family in Israel, that I should be son-in-law to the king?”
