1 Samuel 18:20

20 Meanwhile, Saul's daughter Michal was in love with David. When Saul was told of this, he rubbed his hands in anticipation. "Ah, a second chance. I'll use Michal as bait to get David out where the Philistines will make short work of him." So again he said to David, "You're going to be my son-in-law."

1 Samuel 18:20 Meaning and Commentary

1 Samuel 18:20

And Michal, Saul's daughter, loved David
His youngest daughter fell in love with him, because of the comeliness of his person, his gallant behaviour, his wise conduct, and the general esteem and reputation he was had in, as may be supposed:

and they told Saul, and the thing pleased him;
not that his daughter loved David, or that he should be his son-in-law, but that he should have an opportunity, as he hoped, of destroying David, which he had lost by giving his elder daughter to another; as also of retrieving his credit with the people, which was greatly sunk by using David in the manner he did, who had become the darling of the people.

1 Samuel 18:20 In-Context

18 David, embarrassed, answered, "Do you really mean that? I'm from a family of nobodies! I can't be son-in-law to the king."

19 The wedding day was set, but as the time neared for Merab and David to be married, Saul reneged and married his daughter off to Adriel the Meholathite.

20 Meanwhile, Saul's daughter Michal was in love with David. When Saul was told of this, he rubbed his hands in anticipation. "Ah, a second chance. I'll use Michal as bait to get David out where the Philistines will make short work of him." So again he said to David, "You're going to be my son-in-law."

21

22 Saul ordered his servants, "Get David off by himself and tell him, 'The king is very taken with you, and everyone at court loves you. Go ahead, become the king's son-in-law!'"
