131 'When there ariseth in your midst a prophet, or a dreamer of a dream, and he hath given unto thee a sign or wonder, 2 and the sign and the wonder hath come which he hath spoken of unto thee, saying, Let us go after other gods (which thou hast not known), and serve them, 3 thou dost not hearken unto the words of that prophet, or unto that dreamer of the dream, for Jehovah your God is trying you, to know whether ye are loving Jehovah your God with all your heart, and with all your soul; 4 after Jehovah your God ye walk, and Him ye fear, and His commands ye keep, and to His voice ye hearken, and Him ye serve, and to Him ye cleave.

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.
