Nehemiah 13:23 KJV

21Then I testified against them, and said unto them, Why lodge ye about the wall? if ye do so again, I will lay hands on you. From that time forth came they no more on the sabbath.

22And I commanded the Levites that they should cleanse themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember me, O my God, concerning this also, and spare me according to the greatness of thy mercy.

23In those days also saw I Jews that had married wives of Ashdod, of Ammon, and of Moab:

24And 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.

25And 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.
