הָפַ֣כְתִּי בָכֶ֗ם כְּמַהְפֵּכַ֤ת אֱלֹהִים֙ אֶת־סְדֹ֣ם וְאֶת־עֲמֹרָ֔ה וַתִּהְי֕וּ כְּא֖וּד מֻצָּ֣ל מִשְׂרֵפָ֑ה וְלֹֽא־שַׁבְתֶּ֥ם עָדַ֖י נְאֻם־יְהוָֽה׃ (ס)
I have overthrown some of you, As God overthrew Sodom and Gomorrah, And ye were as a brand plucked out of the burning; Yet have ye not returned unto Me, Saith the LORD.
