4 then the first husband who divorced her can't marry her again. She has made herself ritually unclean, and her remarriage would be an abomination in the Presence of God and defile the land with sin, this land that God, your God, is giving you as an inheritance.

Matthew Henry's Commentary on Deuteronomy 24:4

Commentary on Deuteronomy 24:1-4

(Read Deuteronomy 24:1-4)

Where the providence of God, or his own wrong choice in marriage, has allotted to a Christian a trial instead of a help meet; he will from his heart prefer bearing the cross, to such relief as tends to sin, confusion, and misery. Divine grace will sanctify this cross, support under it, and teach so to behave, as will gradually render it more tolerable.
