10:2 Thus saith the LORD, Learn not the way of the nations, and be not dismayed at the {a} signs of heaven; for the nations are dismayed at them.
(a) God forbids his people to give credit or fear the constellations and conjunctions of stars and planets which have no power of themselves but are governed by him, and their secret motions and influences are not known to man and therefore there can be no certain judgment of it, De 18:9.
10:2 Learn not - The Jews being to live among the Chaldeans in their captivity, where many of them were already, the prophet admonishes them against the Chaldean idolatries, who were all much addicted to astrology. The signs - This was so common among them, that Judicial astrologers, of what nation soever, were generally termed Chaldeans. The Heathen - Leave this to Heathens; it doth not become God's people.
10:1-16 The prophet shows the glory of Israel's God, and exposes the folly of idolaters. Charms and other attempts to obtain supernatural help, or to pry into futurity, are copied from the wicked customs of the heathen. Let us stand in awe, and not dare provoke God, by giving that glory to another which is due to him alone. He is ready to forgive, and save all who repent and believe in the name of his Son Jesus Christ. Faith learns these blessed truths from the word of God; but all knowledge not from that source, leads to doctrines of vanity.
