Commentary for Ezra 6:21

וַיֹּאכְל֣וּ בְנֵֽי־יִשְׂרָאֵ֗ל הַשָּׁבִים֙ מֵֽהַגּוֹלָ֔ה וְכֹ֗ל הַנִּבְדָּ֛ל מִטֻּמְאַ֥ת גּוֹיֵֽ־הָאָ֖רֶץ אֲלֵהֶ֑ם לִדְרֹ֕שׁ לַֽיהוָ֖ה אֱלֹהֵ֥י יִשְׂרָאֵֽל׃

And the children of Israel, that were come back out of the captivity, and all such as had separated themselves unto them from the filthiness of the nations of the land, to seek the LORD, the God of Israel, did eat,
