Moses
Deuteronomy 21:13BSB·traditional attribution

and put aside the clothing of her captivity. After she has lived in your house a full month and mourned her father and mother, you may have relations with her and be her husband, and she shall be your wife.

Matthew Henry Presbyterian @wholebiblehenry

By this law a soldier is allowed to marry his captive if he pleased. For the hardness of their hearts Moses gave them this permission, lest, if they had not had liberty given them to marry such, they should have taken liberty to defile themselves with them, and by such wickedness the camp would have been troubled.

And she shall put the raiment of her captivity from off her,.... Her beautiful garments, and gay apparel, in which she was taken captive; and which tended to stir up the stronger affection for her, and greater desire after her; and therefore, as some think, were ordered to be removed, to abate the ardour of love to her.

Jamieson-Fausset-Brown Reformed @jfbcommentary

THE TREATMENT OF A CAPTIVE TAKEN TO WIFE. (Deu 21:10-23) When thou goest to war . . . and seest among the captives a beautiful woman . . . that thou wouldest have her to thy wife--According to the war customs of all ancient nations, a female captive became the slave of the victor, who had the sole and unchallengeable control of right to her person.
