Michal, Saul's Daughter — 1 Samuel 18:21–24
And Saul said,
I will give him her, that she may be a snare to him, and that the hand of the Philistines may be against him.
Wherefore Saul said to David,
Thou shalt this day be my son-in-law a second time.
And Saul commanded his servants, saying,
Commune with David secretly, and say, Behold, the king hath delight in thee, and all his servants love thee: now therefore be the king's son-in-law.
And Saul's servants spake those words in the ears of David. And David said,
Seemeth it 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 servants of Saul told him, saying,
On this manner spake David.
