Ezra 10:2-3

2And Shechaniah the son of Jehiel, one of the sons of Elam, spoke up and said to Ezra, “We have trespassed against our God, and have taken pagan wives from the peoples of the land; yet now there is hope in Israel in spite of this.

3Now therefore, let us make a covenant with our God to put away all these wives and those who have been born to them, according to the advice of my master and of those who tremble at the commandment of our God; and let it be done according to the law.
