Nehemiah 13:23-25

Young's Literal Translation

²³ Also, in those days, I have seen the Jews [who] have settled women of Ashdod, of Ammon, of Moab.

²⁴ And of their sons, half are speaking Ashdoditish -- and are not knowing to speak Jewish -- and according to the language of people and people.

²⁵ And I strive with them, and declare them vile, and smite certain of them, and pluck off their hair, and cause them to swear by God, `Ye do not give your daughters to their sons, nor do ye take of their daughters to your sons, and to yourselves.
