Deuteronomy 18:12

12 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.

Deuteronomy 18:12 Meaning and Commentary

Deuteronomy 18:12

For all that do these things are an abomination to the
Lord
Not that do all these things, but whoever does any of them, as Jarchi notes; all such persons that use such unlawful methods, or any of them, to gain knowledge; and likewise all those that consult them, and make use of them; and especially it must be very abominable in the people of Israel to encourage such persons and practices, who had the knowledge of the true God, and him to consult on all occasions; had his law and testimony to attend unto as the rule of their conduct, and his prophets to advise with in matters of difficulty; see ( Isaiah 8:20 )

and because of these abominations the Lord thy God doth drive them
out from before thee;
as well as other sins mentioned in ( Leviticus 18:24-28 ) and, as before observed from Cicero, all nations have been addicted to the arts of divination here condemned.

Deuteronomy 18:12 In-Context

10 No one among you is to make his son or daughter pass through the fire, practice divination, tell fortunes, interpret omens, practice sorcery,
11 cast spells, consult a medium or a familiar spirit, or inquire of the dead.
12 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.
13 You must be blameless before the Lord your God.
14 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.
