Ezra 10:4

וַיַּעַן שְׁכַנְיָה בֶן־יְחִיאֵל מִבְּנֵי עולם וַיֹּאמֶר לְעֶזְרָא אֲנַחְנוּ מָעַלְנוּ בֵאלֹהֵינוּ וַנֹּשֶׁב נָשִׁים נָכְרִיּוֹת מֵעַמֵּי הָאָרֶץ וְעַתָּה יֵשׁ־מִקְוֶה לְיִשְׂרָאֵל עַל־זֹֽאת

And Shecaniah the son of Jehiel, one of the sons of Elam, answered and said unto Ezra: ‘We have broken faith with our God, and have married foreign women of the peoples of the land; yet now there is hope for Israel concerning this thing.

וְעַתָּה נִֽכְרָת־בְּרִית לֵאלֹהֵינוּ לְהוֹצִיא כָל־נָשִׁים וְהַנּוֹלָד מֵהֶם בַּעֲצַת אֲדֹנָי וְהַחֲרֵדִים בְּמִצְוַת אֱלֹהֵינוּ וְכַתּוֹרָה יֵעָשֶֽׂה

Now therefore let us make a covenant with our God to put away all the wives, and such as are born of them, according to the counsel of the LORD, and of those that tremble at the commandment of our God; and let it be done according to the law.

וַיָּקָם עֶזְרָא וַיַּשְׁבַּע אֶת־שָׂרֵי הַכֹּהֲנִים הַלְוִיִּם וְכָל־יִשְׂרָאֵל לַעֲשׂוֹת כַּדָּבָר הַזֶּה וַיִּשָּׁבֵֽעוּ

Then arose Ezra, and made the chiefs of the priests, the Levites, and all Israel, to swear that they would do according to this word. So they swore.

וַיָּקָם עֶזְרָא מִלִּפְנֵי בֵּית הָֽאֱלֹהִים וַיֵּלֶךְ אֶל־לִשְׁכַּת יְהוֹחָנָן בֶּן־אֶלְיָשִׁיב וַיֵּלֶךְ שָׁם לֶחֶם לֹֽא־אָכַל וּמַיִם לֹֽא־שָׁתָה כִּי מִתְאַבֵּל עַל־מַעַל הַגּוֹלָֽה

Then Ezra rose up from before the house of God, and went into the chamber of Jehohanan the son of Eliashib; and when he came thither, he did eat no bread, nor drink water; for he mourned because of the faithlessness of them of the captivity.
