Thematic Bible: Following practices of others

Israel, Jehovah will get rid of the nations you attack. You may have their land. Be careful that you are not ensnared to follow them, for they will be destroyed. Do not inquire after their gods, saying: How do these nations serve their gods that I also may do likewise? Do not behave this way toward Jehovah your God, for every abominable act Jehovah hates they have done for their gods. They even burn their sons and daughters in the fire to their gods.

When you come into the land that Jehovah your God gives you, do not follow the disgusting practices of the nations that are there. Do not sacrifice your children in the fires on your altars. Do not let your people practice divination or look for omens or use spells or charms. Do not allow them to consult the spirits of the dead. read more.
Jehovah your God hates people who do these disgusting things. That is why he is driving those nations out of the land as you advance. Be perfect (without blemish) with Jehovah your God. These nations whom you shall possess listened to observers of clouds and to diviners. As for you, Jehovah your God has not allowed you to do so.
