Deuteronomy 24:6

6 the former husband who sent her away shall not be able to return and take her to himself for a wife, after she has been defiled; because it is an abomination before the Lord thy God, and ye shall not defile the land, which the Lord thy God gives thee to inherit.

Deuteronomy 24:6 In-Context

4 And she should go away and be married to another man;
5 and the last husband should hate her, and write for her a bill of divorcement; and should give it into her hands, and send her away out of his house, and the last husband should die, who took her to himself for a wife;
6 the former husband who sent her away shall not be able to return and take her to himself for a wife, after she has been defiled; because it is an abomination before the Lord thy God, and ye shall not defile the land, which the Lord thy God gives thee to inherit.
7 And if any one should have recently taken a wife, he shall not go out to war, neither shall any thing be laid upon him; he shall be free in his house; for one year he shall cheer his wife whom he has taken.
8 Thou shalt not take for a pledge the under millstone, nor the upper millstone; for he who does so takes life for a pledge.
