What does 1 Samuel 18:19 mean?

John Gill's Exposition of the Bible
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.
