Nehemiah 13:23-27 And in those days I saw the Jews who had married women of Ashdod, of Ammon, and of Moab:

Brenton⁽ⁱ⁾ ²³ And in those days I saw the Jews who had married women of Ashdod, of Ammon, and of Moab: ²⁴ and their children spoke half in the language of Ashdod, and did not know how to speak in the Jewish language. ²⁵ And I strove with them and cursed them; and I smote some of them, and plucked off their hair, and made them swear by God, saying, Ye shall not give your daughters to their sons, and ye shall not take of their daughters to your sons. ²⁶ Did not Solomon king of Israel sin thus? though there was no king like him among many nations, and he was beloved of God, and God made him king over all Israel; yet strange women turned him aside. ²⁷ So we will not hearken to you to do all this evil, to break covenant with our God, — to marry strange wives.
