Leviticus 20:17
JPS-1917וְאִ֣ישׁ אֲשֶׁר־יִקַּ֣ח אֶת־אֲחֹת֡וֹ בַּת־אָבִ֣יו א֣וֹ בַת־אִ֠מּ֠וֹ וְרָאָ֨ה אֶת־עֶרְוָתָ֜הּ וְהִֽיא־תִרְאֶ֤ה אֶת־עֶרְוָתוֹ֙ חֶ֣סֶד ה֔וּא וְנִ֨כְרְת֔וּ לְעֵינֵ֖י בְּנֵ֣י עַמָּ֑ם עֶרְוַ֧ת אֲחֹת֛וֹ גִּלָּ֖ה עֲוֺנ֥וֹ יִשָּֽׂא׃
And if a man shall take his sister, his father’s daughter, or his mother’s daughter, and see her nakedness, and she see his nakedness: it is a shameful thing; and they shall be cut off in the sight of the children of their people: he hath uncovered his sister’s nakedness; he shall bear his iniquity.

חסד הוא IT IS A WICKED THING — It is an Aramaic expression, the Hebrew חרפה (disgrace) being in that language חסודא (cf. Onkelos on Genesis 34:14). A Midrashic explanation of it (of חסד הוא) is; If you should say, "But Cain married his sister!" then I reply, Cain's case was an exceptional one; an act of kindness (חסד) was done by the Omnipresent in order that His world might be built up through him (i. e. He made the propagation of the human race possible through this union), as it is said (Psalms 89:3) "The world was built up through חסד, loving-kindness" (Sifra, Kedoshim, Chapter 11 11; Sanhedrin 58b).
