NET

4 her first husband who divorced her is not permitted to remarry her after she has become ritually impure, for that is offensive to the Lord. You must not bring guilt on the land that the Lord your God is giving you as an inheritance.

Darby

4 her first husband, who sent her away, may not take her again to be his wife, after that she is defiled; for it is an abomination before Jehovah; and thou shalt not cause the land to sin, which Jehovah thy God giveth thee for an inheritance.

KJV

4 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.
