Thematic Bible: Following practices of others

"When the Lord your God annihilates the nations before you, which you are entering to take possession of, and you drive them out and live in their land, be careful not to be ensnared by their ways after they have been destroyed before you. Do not inquire about their gods, asking, 'How did these nations worship their gods? I'll also do the same.' You must not do the same to the Lord your God, because they practice for their gods every detestable thing the Lord hates. They even burn their sons and daughters in the fire to their gods.

"When you enter the land the Lord your God is giving you, do not imitate the detestable customs of those nations. No one among you is to make his son or daughter pass through the fire, practice divination, tell fortunes, interpret omens, practice sorcery, cast spells, consult a medium or a familiar spirit, or inquire of the dead. read more.
Everyone who does these things is detestable to the Lord, and the Lord your God is driving out the nations before you because of these detestable things. You must be blameless before the Lord your God. Though these nations you are about to drive out listen to fortune-tellers and diviners, the Lord your God has not permitted you to do this.
