Deuteronomy 27:22

Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. And all the people shall say, Amen.

Deuteronomy 27:22 (KJV)

Context

Deuteronomy records Moses’ final speeches to Israel before they entered the Promised Land. In this chapter, Moses lists curses that the people were to pronounce on specific sins. The whole community was to answer “Amen” to each curse, showing their agreement with God’s judgment. This was not a private ritual but a public covenant ceremony. The people stood together and affirmed that God’s law is just and that those who break it deserve the penalty.

Meaning

This verse condemns sexual relations with a sister, whether she is the daughter of one’s father or one’s mother. The wording covers both full sisters and half sisters. Such a relationship is a serious violation of God’s design for the family. The curse is not a private wish but a public declaration. When the people said “Amen,” they accepted the justice of the penalty and committed themselves to uphold God’s standard. The communal response shows that this sin is not only personal but also harms the whole community. God’s law protects the family and its most vulnerable members.

Biblical connections

The prohibition here builds on Leviticus 18:9, which forbids uncovering the nakedness of a sister. Both passages treat such a relationship as a serious violation of God’s design for the family. The communal “Amen” also echoes the covenant ceremony at Mount Ebal and Gerizim, where Israel bound itself to obey all God’s commands. This curse is part of a larger list that covers hidden sins, reminding Israel that God sees what is done in secret. The New Testament reaffirms the call to sexual purity, urging believers to honor God with their bodies. This verse, therefore, has ongoing relevance for Christians today.

Application

God’s law protects the family and its most vulnerable members. Incest harms individuals, breaks trust, and damages the whole household. Believers today are called to honor God with their bodies and to keep sexual relationships within His boundaries. The church also shares a responsibility to guard these standards and to support those who have been hurt by such sin. The communal “Amen” challenges believers to take a stand against sin and to support one another in pursuing holiness. We are not to remain silent when sin is present, but to affirm God’s justice and care for the wounded.

Reflection

The people’s “Amen” was more than a word; it was a promise to live by God’s law. Hidden sins are still known to God, and the community’s agreement reminds us that holiness is a shared calling. As we read this curse, we can examine our own hearts and renew our commitment to sexual purity and to protecting the family as God designed it. The curse serves as a deterrent and a call to maintain moral boundaries. It also points to the goodness and justice of God’s law, which is given for our well-being.
