אִם־תְּעַנֶּ֣ה אֶת־בְּנֹתַ֗י וְאִם־תִּקַּ֤ח נָשִׁים֙ עַל־בְּנֹתַ֔י אֵ֥ין אִ֖ישׁ עִמָּ֑נוּ רְאֵ֕ה אֱלֹהִ֥ים עֵ֖ד בֵּינִ֥י וּבֵינֶֽךָ׃
If thou shalt afflict my daughters, and if thou shalt take wives beside my daughters, no man being with us; see, God is witness betwixt me and thee.’
Read halakhic rulings (Jewish law) on Genesis 31:50: and classical halakhic sources.
