Ezra 10:1-5

Now while Ezra was praying and making confession, weeping and prostrating himself before the house of God, a very large assembly, men, women, and children, gathered to him from Israel; for the people wept greatly.

Shecaniah the son of Jehiel, one of the sons of Elam, said to Ezra, “We have been unfaithful to our God and have married foreign women from the peoples of the land; yet now there is hope for Israel in spite of this.

So now let’s make a covenant with our God to send away all the wives and their children, following the counsel of my lord and of those who fear the commandment of our God; and let it be done according to the Law.

Arise! For this matter is your responsibility, but we will be with you; be courageous and act.”

Then Ezra stood and made the leading priests, the Levites, and all Israel take an oath that they would do according to this proposal; so they took the oath.
