Nehemiah 13:23-24

13:23 Also in those days I saw the men of Judah who had married women from Ashdod, Ammon, and Moab. 13:24 Half of their children spoke the language of Ashdod (or the language of one of the other peoples mentioned) and were unable to speak the language of Judah.

Psalms 144:7

144:7 Reach down from above!

Grab me and rescue me from the surging water,

from the power of foreigners,

Psalms 144:11

144:11 Grab me and rescue me from the power of foreigners,

who speak lies,

and make false promises.

Malachi 2:11-15

2:11 Judah has become disloyal, and unspeakable sins have been committed in Israel and Jerusalem. For Judah has profaned the holy things that the Lord loves and has turned to a foreign god! 2:12 May the Lord cut off from the community of Jacob every last person who does this, as well as the person who presents improper offerings to the Lord who rules over all!

2:13 You also do this: You cover the altar of the Lord with tears as you weep and groan, because he no longer pays any attention to the offering nor accepts it favorably from you. 2:14 Yet you ask, “Why?” The Lord is testifying against you on behalf of the wife you married when you were young, to whom you have become unfaithful even though she is your companion and wife by law. 2:15 No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.
