Then Darius the king made a decree,.... To make inquiry after the edict of Cyrus, to search the public records for it:
and search was made in the house of the rolls; or "books" r, in a public library or museum:
where the treasures were laid up in Babylon; where things of worth and value were reposited; not only gold, silver, jewels, and precious stones, and things rare and curious, but all sorts of writings relating to the monarchy, and the dominions belonging to it; but it seems it could not be found here, and therefore the king ordered search to be made elsewhere.
