Quick answer

A man who has relations with his sister or half-sister commits a shameful thing and they are to be cut off. Incest within the family is strictly forbidden.

Overview

This addresses incest between siblings, calling it a 'shameful thing' to be publicly judged. The penalty of being 'cut off' means exclusion from the covenant community, and 'he shall bear his iniquity' assigns personal guilt. Such laws protected the family from corruption and upheld the holiness God required of His people.

Christ at the center

Every sacrifice, every priest, and every day of atonement points beyond itself to the one perfect offering and the great High Priest who, by his own blood, makes the unclean holy once for all.

How Leviticus 20:17 points to him is part of the one story that runs through all Scripture — meet Jesus at the heart of the web, or follow a trail that traces him from Genesis to Revelation.
