Cursed be he that lieth with his sister—the Hebrew shochev (שֹׁכֵב, lies with) uses covenant violation language. Leviticus 18:9 and 20:17 explicitly prohibit this incest, calling it chesed (חֶסֶד, disgrace/shame, not to be confused with the positive hesed). The arur (אָרוּר, cursed) formula marks covenant-breaking that severs one from God's blessing and community.
The precision—the daughter of his father, or the daughter of his mother—covers both full and half-siblings, closing any loophole. The communal response And all the people shall say, Amen makes every Israelite complicit in enforcing God's sexual purity standards. To remain silent when such sin occurred was to share in the curse. This anticipates church discipline principles (Matthew 18:15-20; 1 Corinthians 5:1-13).
Historical Context
These twelve curses (Deuteronomy 27:15-26) were proclaimed antiphonally at Mount Ebal as Israel entered Canaan (Joshua 8:30-35). Six tribes stood on Mount Gerizim for blessings, six on Mount Ebal for curses, with the Levites in the valley between declaring covenant conditions. The list emphasizes secret sins—violations done in darkness that human courts might not detect but that still brought divine judgment. Ancient Near Eastern cultures often tolerated incest among royalty (Egyptian pharaohs married siblings), but Israel's law reflected God's holiness.
Questions for Reflection
How does the requirement that 'all the people shall say, Amen' challenge modern individualism that says 'it's none of my business' about others' sin?
What does God's attention to secret sexual sins reveal about His comprehensive concern for holiness in every area of life?
