Deuteronomy 18:9–14: Learning About Demons
Deuteronomy 18:9–14 forbids Israel to learn to imitate the detestable practices of the nations, including consulting familiar spirits and the dead. The sin is adopting those religious methods as a way to gain guidance or power, not merely knowing they exist.
Deuteronomy 18:10–12 and Wearing Angel Numbers
Deuteronomy 18:10–12 forbids Israel to learn and practice the occult arts of the surrounding nations. The text condemns seeking guidance or power from spirits and divination, not wearing a number as decoration, so the question turns on what the wearer is doing with it.
Deuteronomy 18:9–12: Is Studying Demons a Sin?
