The Lord prohibits the Hebrews from practices of divination. Even when God was silent, the people were not to seek false diviners but were called to walk by faith in accordance with the covenant. Two groups are mentioned specifically. Firstly, the Israelites are not to consult with necromancers.
This word refers to those who seek instruction from the dead. A negative example of this is found 1 Samuel 28:1–25 where King Saul visits the witch at Endor.
31 “Do not turn to mediums or necromancers; do not seek them out, and so make yourselves unclean by them: I am the LORD your God.
