29 When you enter the land that you will occupy, your god Yahweh will destroy the people groups that live there as you advance. 30 Watch out after they’ve been destroyed, that you don’t get trapped by curiosity about how they served their gods, and then you end up doing the same. 31 Don’t do that to your god Yahweh, because he hates the disgusting things they’ve done for their gods—even burning their own sons and daughters on altars for their gods.

32 Make sure that you obey all those instructions—don’t add anything to them, or remove anything from them.[ref]
