Nehemiah 13:23-31 - Mixed Marriages Are Condemned
23 Moreover, in these days, saw I the Jews who had married women of Ashdod, of Ammon, of Moab; 24 and, their children, were one-half speaking the language of Ashdod, and understood not how to speak the language of the Jews, - but after the tongue of both people. 25 So I contended with them, and laid a curse upon them, and I smote, from among them, certain men, and pulled out their hair, - and I put them on oath by God, Ye shall not give your daughters unto their sons, nor take of their daughters, for your sons nor for yourselves. 26 Was it not, over these things, that Solomon king of Israel sinned - though, among many nations, there was no king such as he, and he was, beloved by his God, and so God gave him to be king over all Israel, - even him, did foreign women, cause to sin. 27 Unto you, then, shall we hearken, to do all this great wickedness, to act unfaithfully with our God, - by marrying foreign wives?
28 And, one of the sons of Joiada, son of Eliashib the high priest, was son-in-law to Sanballat the Horonite, - therefore I chased him from me.
29 Remember them, O my God, - on account of the Defilings of the Priesthood, and the Covenant of the Priesthood, and of the Levites.
30 So I purified them from everything foreign, - and appointed charges unto the priests and unto the Levites, every one in his work; 31 also for the offering of wood, at times appointed, and for the firstfruits. Remember me, O my God, for good!
