Isaiah 66:24
Westminster Leningrad Codex · Berean Standard Bible
וְיָצְא֣וּ וְרָא֔וּ בְּפִגְרֵי֙ הָאֲנָשִׁ֔ים הַפֹּשְׁעִ֖ים בִּ֑י כִּ֣י תוֹלַעְתָּ֞ם לֹ֣א תָמ֗וּת וְאִשָּׁם֙ לֹ֣א תִכְבֶּ֔ה וְהָי֥וּ דֵרָא֖וֹן לְכָל־ בָּשָֽׂר׃
“As they go forth, they will see the corpses of the men who have rebelled against Me; for their worm will never die, their fire will never be quenched (note: Cited in Mark 9:48), and they will be a horror to all mankind.”
