Ezra 10:2-3

2Then Shecaniah son of Jehiel, one of the sons of Elam, answered and said to Ezra, “We have been unfaithful to our God and have married foreign women from the peoples of the land. But in spite of this, there is still hope for Israel.

3So now let us make a covenant with our God to send away all these women and their offspring, in accordance with the counsel of my lord and of those who fear the commands of our God. Let it be done according to the Torah.
