1st Samuel 18:24

21 and Saul saith, `I give her to him, and she is to him for a snare, and the hand of the Philistines is on him;` and Saul saith unto David, `By the second -- thou dost become my son-in-law to-day.`

22 And Saul commandeth his servants, `Speak unto David gently, saying, Lo, the king hath delighted in thee, and all his servants have loved thee, and now, be son-in-law to the king.`

23 And the servants of Saul speak in the ears of David these words, and David saith, `Is it a light thing in your eyes to be son-in-law to the king -- and I a poor man, and lightly esteemed?`

24 And the servants of Saul declare to him, saying, `According to these words hath David spoken.`

25 And Saul saith, `Thus do ye say to David, There is no delight to the king in dowry, but in a hundred foreskins of the Philistines -- to be avenged on the enemies of the king;` and Saul thought to cause David to fall by the hand of the Philistines.

26 And his servants declare to David these words, and the thing is right in the eyes of David, to be son-in-law to the king; and the days have not been full,

27 and David riseth and goeth, he and his men, and smiteth among the Philistines two hundred men, and David bringeth in their foreskins, and they set them before the king, to be son-in-law to the king; and Saul giveth to him Michal his daughter for a wife.
