Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save thee from these things that shall come upon thee. Isaiah 47:13 Astrology was dealt a serious blow in the book of Daniel. When they could not tell the king his dream, or interpretation for it, they were faced with extermination. (This set the stage for Daniel to reveal the power of God to the heathen). For this cause the king was angry and very furious, and commanded to destroy all the wise men of Babylon. Daniel 2:12
As for astrology and divination by it- Thus saith the LORD, thy redeemer, and he that formed thee from the womb, I am the LORD that maketh all things; that stretcheth forth the heavens alone; that spreadeth abroad the earth by myself; That frustrateth the tokens of the liars, and maketh diviners mad; that turneth wise men backward, and maketh their knowledge foolish; Isaiah 44:24,25 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer. For all that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee. Deuteronomy 18:10-12 For the idols have spoken vanity, and the diviners have seen a lie, and have told false dreams; they comfort in vain: Zechariah 10:2
