Reference for Ezekiel 39:23

וְיָדְע֣וּ הַ֠גּוֹיִם כִּ֣י בַעֲוֺנָ֞ם גָּל֣וּ בֵֽית־יִשְׂרָאֵ֗ל עַ֚ל אֲשֶׁ֣ר מָֽעֲלוּ־בִ֔י וָאַסְתִּ֥ר פָּנַ֖י מֵהֶ֑ם וָֽאֶתְּנֵם֙ בְּיַ֣ד צָרֵיהֶ֔ם וַיִּפְּל֥וּ בַחֶ֖רֶב כֻּלָּֽם׃

And the nations shall know that the house of Israel went into captivity for their iniquity, because they broke faith with Me, and I hid My face from them; so I gave them into the hand of their adversaries, and they fell all of them by the sword.
