Ezra 10:2-3

2And Shechaniah the son of Jehiel, of the sons of Elam, answered and said to Ezra, We have acted unfaithfully toward our 1God, and have taken foreign wives of the peoples of the land; yet now there is hope for Israel concerning this thing.

3And now let us make a covenant with our 2God to put away all the wives, and such as are born of them, according to the counsel of [my] lord, and of those that tremble at the commandments of our 3God; and let it be done according to the law.
