And in the four and twentieth day of the first month
Of the third year of Cyrus, as Jacchiades; or rather of the Jewish year, the month Ab or Nisan, which answers to part of March and April; so that Daniel's fast began on the third day of the month, and lasted to the twenty fourth, in which time was the Jewish passover; and by this it seems it was not now kept; and perhaps in those times was not used to be observed by the Jews in a foreign land: as I was by the side of the great river, which is Hiddekel;
the same with the Tigris, called by both names from the swiftness and rapidity of its motion, "hiddekel" signifying both sharp and swift; and tigris, in the Persian language, a dart; see ( Genesis 2:14 ) . This is the same river the Targum of Jonathan on ( Genesis 2:14 ) calls Diglath; and is by Pliny F5 called Diglito, who observes that it has the name of Tigris from its swiftness; so he says the Medes call an arrow; likewise Curtius F6 takes notice of the same, and says that it is named Tigris from the celerity with which it flows; for in the Persian language they call a dart "tigris": so (dx) signifies in the Hebrew language "sharp" or "polished", as an arrow is; and (lq) , "swift", as an arrow flies, and both make Hiddekel: now this river was near Shushan, where Daniel resided; nay, Benjamin of Tudela F7 says, that the river Hiddekel divides the city of Shushan, over which is a bridge, on one side of which Jews dwelt, at the time he was there; unless he means that it cuts and divides the province of Elam in Persia, he had before been speaking of; and so Diodorus Siculus F8 says, that both Euphrates and Tigris pass through Media into Mesopotamia; wherefore it is no wonder to hear of Daniel by the side of the river Hiddekel or Tigris: here Daniel was, not in vision, but in person, having others with him, as appears from a following verse; by it he was walking, contemplating, praying, or conversing.
