Nehemiah 13:23-31 - Mixed Marriages Are Condemned
23 Also in those days I saw Jews who caused to dwell women, Ashdodites, Ammonites, Moabites: 24 And their sons half speaking the Ashdod dialect, and they not knowing to speak the Judean dialect, and according to the tongue of people and people. 25 And I shall contend with them, and I shall curse them and I shall strike of them men, and I shall make them bald, and cause them to swear by God, If ye shall give your daughters to their sons, and if ye shall lift up from their daughters to your sons and to yourselves. 26 Did not Solomon king of Israel sin concerning these? and in many nations was there not a king like him, and he was loved by his God, and God will give him king over all Israel: also him did women strangers cause to sin. 27 And to you shall we hear to do all this great evil to transgress against our God to cause strange women to dwell.
28 And from the sons of Joiada, son of Eliashib the great priest, was son-in-law to Sanballat the Horonite: and I shall cause him to flee from me.
29 Remember to them, O my God, for the pollutions of the priesthood, and the covenant of the priesthood, and of the Levites.
30 And I cleansed them from every stranger, and I shall set up watches to the priests and to the Levites, a man in his work. 31 And for the bringing near the woods in the times appointed, and for the first-fruits. Remember to me, O my God for good.
