1 Samuel 18:3+ - Bíblia Online

And it came to pass, when he had made an end of speaking to Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul. 
And Saul took him that day, and would not let him go home anymore to his father's house. 
Then Jonathan and David made a covenant, because he loved him as his own soul. 
And Jonathan stripped himself of the robe that was on him, and gave it to David, and his apparel, even to his sword, and to his bow, and to his belt. 
And David went out wherever Saul sent him, [and] behaved himself wisely: and Saul set him over the men of war, and it was good in the sight of all the people, and also in the sight of Saul's slaves. 
And 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. 
And the women sang one to another as they played, and said, Saul has slain his thousands, And David his ten thousands. 
And Saul was very angry, and this thing was evil in his eyes; and he said, They have ascribed to David ten thousands, and to me they have ascribed but thousands: and what can he have more but the kingdom? 
And Saul eyed David from that day and forward. 
And it came to pass on the next day, that an evil spirit from God came mightily on 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; 
and Saul cast the spear; for he said, I will strike David even to the wall. And David avoided out of his presence twice. 
And Saul was afraid of David, because Yahweh was with him, and had departed from Saul. 
Therefore Saul removed him from himself, and made him his captain over a thousand; and he went out and came in before the people. 
And David behaved himself wisely in all his ways; and Yahweh was with him. 
And 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. 
And Saul said to David, Look, 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. 
And 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? 
But it came to pass at the time when Merab, Saul's daughter, should have been given to David, that she was given to Adriel the Meholathite as wife. 
And Michal, Saul's daughter, loved David: and they told Saul, and the thing was right in his eyes. 
And Saul said, I will give her to him, that she may be a snare to him, and that the hand of the Philistines may be against him. Therefore Saul said to David, You will this day be my son-in-law a second time. 
And Saul commanded his slaves, [saying], Commune with David secretly, and say, Look, the king has delight in you, and all his slaves love you: now therefore be the king's son-in-law. 
And Saul's slaves spoke those words in the ears of David. And David said, Does it seem to you{+} a light thing to be the king's son-in-law, seeing that I am a poor man, and lightly esteemed? 
And the slaves of Saul told him, saying, On this manner spoke David. 
And Saul said, Thus you{+} will say to David, The king does not desire any dowry, but a hundred foreskins of the Philistines, to be avenged of the king's enemies. Now Saul thought to make David fall by the hand of the Philistines. 
And when his slaves told David these words, it pleased David well to be the king's son-in-law. And the days were not expired; 
and David arose and went, he and his men, and slew of the Philistines two hundred men; and David brought their foreskins, and they gave them in full number to the king, that he might be the king's son-in-law. And Saul gave him Michal his daughter as wife. 
And Saul saw and knew that Yahweh was with David; and Michal, Saul's daughter, loved him. 
And Saul was yet the more afraid of David; and Saul was David's enemy continually. 
Then the princes of the Philistines went forth: and it came to pass, as often as they went forth, that David behaved himself more wisely than all the slaves of Saul; so that his name was much set by.
