Jeremiah 49:16

Edom had deceived herself by thinking that other nations would be too afraid of her apparently impregnable location to attack her. But the Lord promised to bring her down and to humble her arrogance (cf. Obadiah 1:1-4). "The rock" is a translation of Sela, a site near the city carved out of rock near Bozrah, later called Petra (in Greek).
