To not inquire after other gods means that the Israelites were forbidden to explore or imitate the ways in which pagans worshiped their false gods. Curiosity about how the nations served their idols was dangerous because it opened the door to syncretism, compromise, and eventual apostasy.
“Take heed to yourself that you are not ensnared to follow them, after they are destroyed from before you, and that you do not inquire after their gods, saying, ‘How did these nations serve their gods? I also will do likewise.'” (Deuteronomy 12:30)
God knew the human tendency to be drawn to what is novel or spiritually appealing, especially when it is culturally accepted or emotionally satisfying. But no matter how attractive the practices appeared, they were detestable to the Lord.
“You shall not worship the Lord your God in that way; for every abomination to the Lord which He hates they have done to their gods…” (Deuteronomy 12:31)
Inquiring after other gods was not mere academic interest. It was the first step toward justification and imitation. God demanded exclusive worship and warned that even investigation could lead to downfall. Israel was to hold fast to God’s revealed Word and reject all foreign religious ideas, no matter how widespread or intriguing.
