This adjective describes someone in a state of exultation—jubilant, triumphant rejoicing. In Isaiah 5:14, it characterizes those who celebrate in Jerusalem, oblivious to coming judgment. The prophet portrays Sheol opening wide to swallow the nobles, masses, and 'the exulting one' of Jerusalem—those who feast and carouse without regard for God's work. The term captures boisterous, self-confident celebration, which in Isaiah's context becomes tragic irony as those reveling are about to descend into death. It emphasizes the spiritual danger of comfortable self-satisfaction.
