15 "But be very careful! You did not see the Lord 's form on the day he spoke to you from the heart of the fire at Mount Sinai. 16 So do not corrupt yourselves by making an idol in any form-whether of a man or a woman, 17 an animal on the ground, a bird in the sky, 18 a small animal that scurries along the ground, or a fish in the deepest sea. 19 And when you look up into the sky and see the sun, moon, and stars-all the forces of heaven-don't be seduced into worshiping them. The Lord your God gave them to all the peoples of the earth.
Matthew Henry's Commentary on Deuteronomy 4:15-19
Commentary on Deuteronomy 4:1-23
(Read Deuteronomy 4:1-23)
The power and love of God to Israel are here made the ground and reason of a number of cautions and serious warnings; and although there is much reference to their national covenant, yet all may be applied to those who live under the gospel. What are laws made for but to be observed and obeyed? Our obedience as individuals cannot merit salvation; but it is the only evidence that we are partakers of the gift of God, which is eternal life through Jesus Christ, Considering how many temptations we are compassed with, and what corrupt desires we have in our bosoms, we have great need to keep our hearts with all diligence. Those cannot walk aright, who walk carelessly. Moses charges particularly to take heed of the sin of idolatry. He shows how weak the temptation would be to those who thought aright; for these pretended gods, the sun, moon, and stars, were only blessings which the Lord their God had imparted to all nations. It is absurd to worship them; shall we serve those that were made to serve us? Take heed lest ye forget the covenant of the Lord your God. We must take heed lest at any time we forget our religion. Care, caution, and watchfulness, are helps against a bad memory.
