'Heavy' in the Bible

And he sendeth thither horses and chariot, and a heavy force, and they come in by night, and go round against the city.

And the king of Asshur sendeth Tartan, and the chief of the eunuchs, and the chief of the butlers, from Lachish, unto king Hezekiah, with a heavy force, to Jerusalem, and they go up and come in to Jerusalem, and they go up, and come in and stand by the conduit of the upper pool that is in the highway of the fuller's field.
