Deuteronomy 24:8 In-Context

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.
9 And if a man should be caught stealing one of his brethren of the children of Israel, and having overcome him he should sell him, that thief shall die; so shalt thou remove that evil one from yourselves.
10 Take heed to thyself in the plague of leprosy: thou shalt take great heed to do according to all the law, which the priests the Levites shall report to you; take heed to do, as I have charged you.
