Deuteronomy 24:3-4

And {if} the latter husband hate her, and write her a bill of divorcement, and giveth {it} in her hand, and sendeth her out of his house; or if the latter husband die, which took her {to be} his wife; Her former husband, which sent her away, may not take her again to be his wife, after that she is defiled; for that {is} abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee {for} an inheritance.
