Why, then, have you disobeyed my commands? Why did you do this evil thing? You had Uriah killed in battle; you let the Ammonites kill him, and then you took his wife!
Then Saul said to David, “Here is my older daughter Merab. I will give her to you as your wife on condition that you serve me as a brave and loyal soldier, and fight the Lord's battles.” (Saul was thinking that in this way the Philistines would kill David, and he would not have to do it himself.)
He said to himself, “I'll give Michal to David; I will use her to trap him, and he will be killed by the Philistines.” So for the second time Saul said to David, “You will be my son-in-law.”
and Saul ordered them to tell David: “All the king wants from you as payment for the bride are the foreskins of a hundred dead Philistines, as revenge on his enemies.” (This was how Saul planned to have David killed by the Philistines.)
