1 Samuel 18:21-22

Leeser(i) 21 And Saul said, I will give her to him, that she may become unto him a snare, and that the hand of the Philistines may be against him. Wherefore Saul said to David, Through the second shalt thou this day become my son-in-law. 22 And Saul commanded his servants, Speak to David secretly, saying, Behold, the king hath delight in thee, and all his servants love thee; and now thou must become the king’s son-in-law.
