LXX Gen 14:10

ἡ δὲ κοιλὰς ἡ ἁλυκὴ φρέατα ἀσφάλτου. ἔφυγεν δὲ βασιλεὺς Σοδόμων καὶ βασιλεὺς Γομόρρας, καὶ ἐνέπεσαν ἐκεῖ οἱ δὲ καταλειφθέντες εἰς τὴν ὀρινὴν ἔφυγον.

Now the Valley of Siddim was full of tar pits, and as the kings of Sodom and Gomorrah fled, some men fell into the pits, but the survivors fled to the hill country.
