Nehemiah 13:24

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

22 And 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.

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

24 And their children spoke half in the speech of Ashdod, and could not speak in the Jews language, but according to the language of each people.

25 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 to their sons, nor take their daughters to your sons, or for yourselves.

26 Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved by his God, and God made him king over all Israel: nevertheless even him did outlandish women cause to sin.

27 Shall we then hearken to you to do all this great evil, to transgress against our God in marrying foreign wives?
