Ezra 10:2-3

2Then Shecaniah son of Jehiel, from the descendants of Elam, addressed Ezra: “We have been unfaithful to our God by marrying foreign women from the local peoples. Nonetheless, there is still hope for Israel in this regard.

3Therefore let us enact a covenant with our God to send away all these women and their offspring, in keeping with your counsel, my lord, and that of those who respect the commandments of our God. And let it be done according to the law.
