13:1 If there arise among you a prophet, or a dreamer of {a} dreams, and giveth thee a sign or a wonder,
(a) Who says that he has things revealed to him in dreams.
13:1 A dreamer of dreams - One that pretends God hath revealed himself to him by visions or dreams. Giveth a sign or wonder - That is, shall foretell some strange and wonderful thing.
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.
