3. Ezra 9:2

4. Neh. 13:23-29

   • "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?  And one of the sons of Joiada, the son of Eliashib the high priest, was son in law to Sanballat the Horonite: therefore I chased him from me.  Remember them, O my God, because they have defiled the priesthood, and the covenant of the priesthood, and of the Levites."

   3. "Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of YHVH which he loved, and hath married the daughter of a strange god."

6. 2 Cor. 6:14

   • "Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?"

7. 1 Cor. 7:13-16

   • "And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him.  For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.  But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God hath called us to peace.  For what knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?"
