Melachim Bais 6:14-17

Therefore sent he there susim, and merkavot, and a strong army contingent; and they came by lailah, and surrounded the ir. And when the mesharet (minister, servant) of the Ish HaElohim was risen early, and went forth, hinei, an army surrounded the ir with susim and merkavot. And his na'ar said unto him, Alas, adoni! What shall we do? And he answered, Fear not; for they that be with us are rabbim (many) more than they that be with them. And Elishah davened, and said, HASHEM, now, open his eyes, that he may see. And HASHEM opened the eyes of the na'ar and he saw; and, hinei, the har was full of susim and merkavot of eish all around Elishah.
