Isaiah 39:6

Behold, the days come that all that Is in thine house, all the material riches which he had amassed, of which he had shown himself so proud and vain, at least in a measure, and that which thy fathers have laid up in store until this day, everything that had escaped being paid as tribute, especially the precious metals inside the Temple, shall be carried to Babylon; nothing shall be left, saith the Lord. This was the first direct prophecy foretelling the Babylonian captivity.
