Nehemiah 10:28-31

28Malluch, Harim, and Baanah.

29“Now the rest of the people —the kohanim, the Levites, the gatekeepers, the singers, the Temple servants, and all who had separated themselves from the peoples of the lands for the sake of the Torah of God, along with their wives, their sons and their daughters who were able to understand—

30all join their brothers the nobles, and enter into a curse and an oath to walk in the Torah of God given through Moses the servant of God, and to keep and do all the mitzvot of Adonai our Lord, along with His ordinances and His statutes.

31“Furthermore, we will not give our daughters to the peoples of the land, and we will not take their daughters for our sons.
