131 If ever you have among you a prophet or a dreamer of dreams and he gives you a sign or a wonder, 2 And the sign or the wonder takes place, and he says to you, Let us go after other gods, which are strange to you, and give them worship; 3 Then give no attention to the words of that prophet or that dreamer of dreams: for the Lord your God is testing you, to see if all the love of your heart and soul is given to him. 4 But keep on in the ways of the Lord your God, fearing him and keeping his orders and hearing his voice, worshipping him and being true to him.

Commentary on Deuteronomy 13:1-5
(Read Deuteronomy 13:1-5)
Moses had cautioned against the peril that might arise from the Canaanites. Here he cautions against the rise of idolatry among themselves. It is needful for us to be well acquainted with the truths and precepts of the Bible; for we may expect to be proved by temptations of evil under the appearance of good, of error in the guise of truth; nor can any thing rightly oppose such temptations, but the plain, express testimony of God's word to the contrary. And it would be a proof of sincere affection for God, that, notwithstanding specious pretences, they should not be wrought upon the forsake God, and follow other gods to serve them.
