For Tyrus has for herself built a fortress. The Prophet shows by these words how very cautious or prudent the Syrians had been; for they fortified themselves by strongholds, and thought themselves to be beyond the reach of danger. He then adds, and heaped to herself silver as dust, and gold as the mire of the streets, that is, accumulated wealth above measure; for he mentions “dust” and “mire” as signifying an immense heap; as though he had said, “They have worthless heaps of silver and gold for their vast abundance”. He no doubt includes silver and gold in the fortress which he mentions; for I do not confine the word fortress only to towers and strongholds; but the Prophet, as I think, states generally, that Tyrus was so furnished and fortified with wealth, forces, and all kinds of defences, that it thought itself impregnable.
There is a striking correspondence between צור, tsur, and מצור, metsur צור, Tsur, he says, has built מצור, metsur, a fortress. It is a paronomasia worthy of notice, but cannot be retained in Latin.
