1 Samuel 18:19

19 And when the time came that Merab, the daughter of Saul, should have been given wife to David, she was given wife to Adriel Meholathite. (But when the time came that Merab, Saul's daughter, should have been given for a wife to David, instead she was given for a wife to Adriel the Meholathite.)

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 And Saul said to David, Lo! mine elder daughter Merab, I shall give her (for a) wife to thee; only be thou a strong man, and fight thou the Lord's battles. Forsooth Saul areckoned, and said, Mine hand be not in him, but the hand of Philistines be on him (But Saul reckoned, and said to himself, My hand shall not be upon him, but the hands of the Philistines shall be upon him).

18 And David said to Saul, Who am I, either what is my life, either (what is) the family of my father in Israel, that I (should) be made the son-in-law of the king?

19 And when the time came that Merab, the daughter of Saul, should have been given wife to David, she was given wife to Adriel Meholathite. (But when the time came that Merab, Saul's daughter, should have been given for a wife to David, instead she was given for a wife to Adriel the Meholathite.)

20 Forsooth David loved Michal, the [tother] daughter of Saul; and it was told to Saul, and it pleased him.

21 And Saul said, I shall give her to him, that it be to him into cause of stumbling, and the hand of Philistines be upon him. Therefore Saul said to David, In (wedding one of my) two daughters thou shalt be my son-in-law today. (And Saul said, I shall give her to him, so that she shall become a cause of stumbling to him, and so that the hands of the Philistines shall be upon him. And so Saul said to David, By wedding my younger daughter, on that day thou shalt become my son-in-law.)
