Daniel 10:4 - Joseph Benson’s Commentary on the Old and New Testaments

In the four and twentieth day of the first month “Nisan, if the Jewish computation be admitted; that is, the month in which was the paschal solemnity. Hence commentators have observed, from this fact of the prophet, that the Jews did not observe their festivals except in their own country, and in the place which God had appointed; but if the Persian computation should be followed, which seems not improbable, as the prophet dates his vision from the third year of Cyrus the Persian, then the month will be different.” I was by the side Or, on the bank, of the great river Hiddekel “Syriac, the Euphrates; but the Vulgate reads, the Tigris; the Greek and Arabic, Tigris-eddekel. It was probably near the junction of the two rivers, which was about Seleucia and Ctesiphon, in some part of Susiana, that the prophet was placed.” Wintle.
