Then king Darius wrote unto all people, nations, and languages, that dwell in all the earth; Peace be multiplied unto you.
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:
Peace be multiplied unto you; an increase of all kind of prosperity; an usual salutation or wish with the eastern people.
