Matthew Poole and continuators on Deuteronomy 21:14

14 And it shall be, if thou have no delight in her , then thou shalt let her go whither she will, but thou shalt not sell her at all for mony, thou shalt not make merchandise of her , because thou hast humbled her .

Either 1. after thou hast married her, and so this is a permission of a Divorce, which being indulged towards an Israelitish woman, was not likely to be denied towards a stranger. Or rather 2. before thy marriage: for it is not probable, that God having given him competent time for the trial of his affections to her before he was permitted to marry her would suffer him upon so sleight an occasion within a day or two after so solemn a contract to send her away: nor is there a word spoken here of any Divorce.

(i. e.) Make gain of her, either by using her to thy own servile works, or by prostituting her to the lusts or to the service of others.

(i. e.) Lain with her as this phrase is oft used, as Gen. 34. 2. Deut. 22. 24, 29. Iudg. 19. 24. Ezek. 22. 10, 11.
