וְעֵ֣מֶק הַשִׂדִּ֗ים בֶּֽאֱרֹ֤ת בֶּאֱרֹת֙ חֵמָ֔ר וַיָּנֻ֛סוּ מֶֽלֶךְ־סְדֹ֥ם וַעֲמֹרָ֖ה וַיִּפְּלוּ־שָׁ֑מָּה וְהַנִּשְׁאָרִ֖ים הֶ֥רָה נָּֽסוּ׃
Now the vale of Siddim was full of slime pits; and the kings of Sodom and Gomorrah fled, and they fell there, and they that remained fled to the mountain.
Targum Jonathan on Genesis
And the valley of the gardens had many pits filled with bitumen: and the kings of Sedom and Amora fled away, and fell there; and they who were left fled to the mountains.
