1 Samuel 18:19 Meaning and Commentary

1 Samuel 18:19

But it came to pass, at the time when Merab, Saul's daughter,
should have been given to David
Either when the giving of her to him was talked of, or when the time fixed for her marriage was come:

that she was given to Adriel the Meholathite to wife:
Saul either having in reality never designed she should be given to David, only proposed it to please the people, or to affront David, and expose him to shame and confusion by the step he meant to take, or however he soon changed his mind; though Abarbinel's notion is, that the young lady had disposed of herself to this person without her father's knowledge, which seems not likely; the person she was given to was the son of Barzillai the Meholathite, ( 2 Samuel 21:8 ) ; and some have observed, as the curse of God on this match, that all her sons were delivered to the Gibeonites, and hanged up, as related in the same place; for though these sons are said to be brought up by Michal, they were bore by Merab to him.

1 Samuel 18:19 In-Context

17 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.)
18 David answered, "Who am I and what is my family that I should become the king's son-in-law?"
19 But when the time came for Merab to be given to David, she was given instead to a man named Adriel from Meholah.
20 Saul's daughter Michal, however, fell in love with David, and when Saul heard of this, he was pleased.
21 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."
