Ezra 10:2-3

2Then Shekaniah son of Jehiel, one of the descendants of Elam, said to Ezra, “We have been unfaithful to our God by marrying foreign women from the peoples around us. But in spite of this, there is still hope for Israel.

3Now let us make a covenant before our God to send away all these women and their children, 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 Law.
