(Verse 6.) Cross over, O sea! Cry out, you who dwell on the island! Once again, they have carried Carthage across the sea and to Tharsis, seventy ships. We read in the histories of the Assyrians that the besieged Tyrians, seeing no hope of escape, fled to Carthage, either to other islands of the Ionian and Aegean seas. Hence it is said in Ezekiel: No wages were given to him, nor to his army from Tyre (Ezek. 29); because all the wealth of the city has been transferred, and all its nobles have abandoned it empty.
