כִּֽי־שָׂנֵ֣א שַׁלַּ֗ח אָמַ֤ר יְהוָה֙ אֱלֹהֵ֣י יִשְׂרָאֵ֔ל וְכִסָּ֤ה חָמָס֙ עַל־לְבוּשׁ֔וֹ אָמַ֖ר יְהוָ֣ה צְבָא֑וֹת וְנִשְׁמַרְתֶּ֥ם בְּרוּחֲכֶ֖ם וְלֹ֥א תִבְגֹּֽדוּ׃ (ס)
For I hate putting away, Saith the LORD, the God of Israel, And him that covereth his garment with violence, Saith the LORD of hosts; Therefore take heed to your spirit, That ye deal not treacherously.
Rashi on Malachi
If you hate [her], send [her] away Our Sages differ concerning it in tractate Gittin (90b). Some of them say: If you hate her, send her away with a bill of divorcement, so that she can marry someone else.
Rashi on Malachi
For injustice shall cover his garment But this - is it proper to do, that you spread your cloak over her to keep her for you as your wife, and you provoke her and torment her constantly?
