And the word rendered breadth, may be rendered the extension or the length of it; it being improbable that the king should give orders about the breadth, and none about the length of it.

For that empire sensibly declined ever after, 'till it was wholly destroyed. Verse 14Through the prophesying - This is a seasonable intimation that this great and unexpected success was not to be ascribed to chance, or to the kindness or good humour of Darius, but unto God only, who by his prophets had required and encouraged them to proceed in the work, and by his mighty power disposed Darius's heart to such kind and noble purposes. Verse 21Children of Israel - Probably some out of each of the twelve tribes. Verse 22Joyful - He had given them both cause to rejoice, and hearts to rejoice.
