2 Peter 2:20–213 votes
For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
Deuteronomy 32:26–272 votes
I said, I would scatter them into corners, I would make the remembrance of them to cease from among men: Were it not that I feared the wrath of the enemy, lest their adversaries should behave themselves strangely, and lest they should say, Our hand is high, and the Lord hath not done all this.
Nehemiah 13:23–272 votes
In those days also saw I Jews that had married wives of Ashdod, of Ammon, and of Moab: And their children spake half in the speech of Ashdod, and could not speak in the Jews’ language, but according to the language of each people. And I contended with them, and cursed them, and smote certain of them, and plucked off their hair, and made them swear by God, saying, Ye shall not give your daughters unto their sons, nor take their daughters unto your sons, or for yourselves. Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved of his God, and God made him king over all Israel: nevertheless even him did outlandish women cause to sin. Shall we then hearken unto you to do all this great evil, to transgress against our God in marrying strange wives?
