Deuteronomy 13:2

2 and that sign or wonder he has promised you comes about, but he says, 'Let us follow other gods,' which you have not known, 'and let us worship them,'

Deuteronomy 13:2 Meaning and Commentary

Deuteronomy 13:2

And the sign and wonder come to pass whereof he spake unto
thee
The sign he promised to give, or the miracle he proposed to do, to show the reality of his mission, and the truth of his doctrine, which is performed, or seemingly performed, by legerdemain, by magic art, or by the help of the devil; which the Lord sometimes suffered for the trial of the faith and obedience of his people, and for the hardening of others in their unbelief, and which issues in their destruction; see ( 2 Thessalonians 2:9-12 ) ,

saying, let us go after other gods (which thou hast not known), and let
us serve them;
other gods besides the one living and true God, the Creator of all things; strange gods, the idols of the people, as the Targum of Jonathan; such as they had never heard of, nor had any knowledge of, nor any benefit from, as they had of the Lord their God. Now the doctrines of these, and of their worship, are what the false prophet or dreamer is supposed to come with, and inculcate into the minds of the people; and for the confirmation of which, and in order to draw them into the reception of them, and act according to them, he proposed to give a sign or wonder.

Deuteronomy 13:2 In-Context

1 "If a prophet or someone who has dreams arises among you and proclaims a sign or wonder to you,
2 and that sign or wonder he has promised you comes about, but he says, 'Let us follow other gods,' which you have not known, 'and let us worship them,'
3 do not listen to that prophet's words or to that dreamer. For the Lord your God is testing you to know whether you love the Lord your God with all your heart and all your soul.
4 You must follow the Lord your God and fear Him. You must keep His commands and listen to His voice; you must worship Him and remain faithful to Him.
5 That prophet or dreamer must be put to death, because he has urged rebellion against the Lord your God who brought you out of the land of Egypt and redeemed you from the place of slavery, to turn you from the way the Lord your God has commanded you to walk. You must purge the evil from you.
