Deuteronomy 13:2

2 and this thing that he said befalleth, and he saith to thee, Go we, and follow we alien gods, which thou knowest not, and serve we them, (and what he said befalleth, and then he saith to thee, Now let us go, and follow foreign, or other, gods, which thou knowest not, and let us serve 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 riseth in the midst of thee, either he that saith himself to have seen a dream, and he before-saith a sign, and a wonder to come after, (When a prophet riseth up in the midst of thee, or him who saith that he hath seen a dream, and he speaketh of a sign, or a wonder, before that it cometh,)

2 and this thing that he said befalleth, and he saith to thee, Go we, and follow we alien gods, which thou knowest not, and serve we them, (and what he said befalleth, and then he saith to thee, Now let us go, and follow foreign, or other, gods, which thou knowest not, and let us serve them,)

3 thou shalt not hear the words of that prophet, either of that dreamer; for your Lord God assayeth you, that he know openly whether ye love him, either nay, in all your heart, and in all your soul. (thou shalt not listen to the words of that prophet, or of that dreamer; for the Lord your God trieth, or testeth, you, to clearly know whether ye love him, or not, with all your heart, and with all your soul.)

4 Follow ye your Lord God, and dread ye him; keep ye his commandments, and hear ye his voice; ye shall serve him, and ye shall cleave to him. (Follow ye the Lord your God, and fear ye him; obey ye his commandments, and listen ye to his voice; ye shall serve him, and ye shall cleave to him.)

5 And that prophet, either (that) feigner of dreams, shall be slain; for he spake (so) that he should turn you away from your Lord God, that led you out of the land of Egypt, and again-bought you from the house of servage (and bought you back, or redeemed, or ransomed, you, from the house of servitude, or of slavery), (so) that he make thee to err from the way that thy Lord God commanded to thee; and in (the) killing of him thou shalt do away evil from the midst of thee.
