Charles Spurgeon Commentary Jeremiah 10:1-2

"Hear ye the word which Jehovah speaketh unto you, O house of Israel: thus saith Jehovah, Learn not the way of the nations, and be not dismayed at the signs of heaven; for the nations are dismayed at them." — Jeremiah 10:1-2 (ASV)

Among pagans, if certain stars were in conjunction, it was considered unlucky; and certain days of the week were also regarded as unlucky, just as even today, there are people who think that it is very unfortunate to begin anything on a Friday. There are a great many foolish superstitions floating about this silly world, but you Christian people should never allow such follies to have any influence on you. Neither the fiends of hell, nor the stars of heaven, can ever injure those who put their trust in God.
