Ezra 10:2-3

2Then Shecaniah son of Jehiel, an Elamite, said to Ezra: “We have been unfaithful to our God by marrying foreign women from the people of the land, yet in spite of this, there is hope for Israel. 3So now let us 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.
