Then King Darius
Being thoroughly convinced of the miracle, and of the powerful
interposition of divine Providence in it, and of the omnipotence
of God, and of his concern in the government of the world; that
all might be acquainted with the same, wrote unto all
people, nations, and languages, that dwell in all the
earth;
he being at the head of the Babylonish monarchy, which included
many nations and people of various languages; and which was
increased, and still increasing, by the victories of Cyrus, who
was partner with him in the empire; see ( Daniel 3:4 Daniel 3:29 ) :
peace be multiplied unto you;
an increase of all kind of prosperity; an usual salutation or
wish with the eastern people.
