Ezra 10:2-3

2Then Shecaniah son of Jehiel, an Elamite, responded to Ezra, “We have been unfaithful to our God by marrying foreign women from the surrounding peoples, but there is still hope for Israel in spite of this.

3Therefore, let’s make a covenant before our God to send away all the foreign wives and their children, according to the counsel of my lord and of those who tremble at the command of our God. Let it be done according to the law.
