1st Samuel 18:23

20 Michal, Saul`s daughter, loved David: and they told Saul, and the thing pleased him.

22 Saul commanded his servants, [saying], Commune with David secretly, and say, Behold, the king has delight in you, and all his servants love you: now therefore be the king`s son-in-law.

23 Saul`s servants spoke those words in the ears of David. David said, Seems it to you a light thing to be the king`s son-in-law, seeing that I am a poor man, and lightly esteemed?

24 The servants of Saul told him, saying, On this manner spoke David.

25 Saul said, Thus shall you tell David, The king desires no dowry except one 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.

26 When his servants told David these words, it pleased David well to be the king`s son-in-law. The days were not expired;
