לֹא־יוּכַ֣ל בַּעְלָ֣הּ הָרִאשׁ֣וֹן אֲשֶֽׁר־שִׁ֠לְּחָהּ לָשׁ֨וּב לְקַחְתָּ֜הּ לִהְי֧וֹת ל֣וֹ לְאִשָּׁ֗ה אַחֲרֵי֙ אֲשֶׁ֣ר הֻטַּמָּ֔אָה כִּֽי־תוֹעֵבָ֥ה הִ֖וא לִפְנֵ֣י יְהוָ֑ה וְלֹ֤א תַחֲטִיא֙ אֶת־הָאָ֔רֶץ אֲשֶׁר֙ יְהוָ֣ה אֱלֹהֶ֔יךָ נֹתֵ֥ן לְךָ֖ נַחֲלָֽה׃ (ס)
her former husband, who 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.
Targum Jonathan on Deuteronomy
it shall not be in the power of the first husband who dismissed her at the beginning to return and take her to be with him as his wife, after that she hath been defiled; for that is an abomination before the Lord: for the children whom she might bear should not be made abominable, or the land which the Lord your God giveth you to inherit become obnoxious to the plague.
