Deuteronomy 20:18

³⁰be careful that you are not ensnared to follow them after they are destroyed from before you, and that you not inquire after their gods, saying, “How do these nations serve their gods? I will do likewise.” ³¹You shall not do so to the LORD your God; for every abomination to the LORD, which he hates, they have done to their gods; for they even burn their sons and their daughters in the fire to their gods.

³³They shall not dwell in your land, lest they make you sin against me, for if you serve their gods, it will surely be a snare to you.”

¹¹Have no fellowship with the unfruitful deeds of darkness, but rather even reprove them.

¹⁶and you take of their daughters to your sons, and their daughters play the prostitute after their gods, and make your sons play the prostitute after their gods.

¹³know for a certainty that the LORD your God will no longer drive these nations from out of your sight; but they shall be a snare and a trap to you, a scourge in your sides, and thorns in your eyes, until you perish from off this good land which the LORD your God has given you.

¹⁷Therefore “‘Come out from among them, and be separate,’ says the Lord. ‘Touch no unclean thing. I will receive you.

⁴For that would turn away your sons from following me, that they may serve other gods. So the LORD’s anger would be kindled against you, and he would destroy you quickly. ⁵But you shall deal with them like this: you shall break down their altars, dash their pillars in pieces, cut down their Asherah poles, and burn their engraved images with fire.

³⁴They didn’t destroy the peoples, as the LORD commanded them, ³⁵but mixed themselves with the nations, and learned their works. ³⁶They served their idols, which became a snare to them. ³⁷Yes, they sacrificed their sons and their daughters to demons. ³⁸They shed innocent blood, even the blood of their sons and of their daughters, whom they sacrificed to the idols of Canaan. The land was polluted with blood. ³⁹Thus they were defiled with their works, and prostituted themselves in their deeds. ⁴⁰Therefore the LORD burned with anger against his people. He abhorred his inheritance.

¹⁴If any man doesn’t obey our word in this letter, note that man and have no company with him, to the end that he may be ashamed.

³³Don’t be deceived! “Evil companionships corrupt good morals.”
