Defilement. Chapters 11–15 focus on the concept of “clean” and “unclean” in the areas of food (11), birth (12), disease (13–14), and normal bodily functions (15). Although the laws certainly served a practical hygienic purpose, there was also a spiritual principle involved. As God’s people, Israel had to be separated from everything that God called unclean. Other nations might be able to do those things, but the Jews could not (vv. 44–45). Defilement spreads, and one person’s carelessness could affect many people.
Discernment. If they wanted to be pleasing to God, the people had to exercise discernment (vv. 46–47); the priests were supposed to teach them God’s will (Ezek. 44:23). The dietary laws were temporary (Mark 7:14–23; Acts 10:9–18; 1 Tim. 4:1–5), but the principle is permanent: believers must have discernment and avoid what is unclean (2 Cor. 7:1; Phil. 1:9–11; Heb. 5:14).
