Reference for Jeremiah 50:33

כֹּ֤ה אָמַר֙ יְהוָ֣ה צְבָא֔וֹת עֲשׁוּקִ֛ים בְּנֵי־יִשְׂרָאֵ֥ל וּבְנֵי־יְהוּדָ֖ה יַחְדָּ֑ו וְכָל־שֹֽׁבֵיהֶם֙ הֶחֱזִ֣יקוּ בָ֔ם מֵאֲנ֖וּ שַׁלְּחָֽם׃

Thus saith the LORD of hosts: The children of Israel and the children of Judah are oppressed together; And all that took them captives hold them fast; They refuse to let them go.
