What does Daniel 8:2 mean?
In his vision (Daniel 8:1), Daniel sees himself in Susa, the capital city of the Persians. Though he was physically in Babylon, his perception was more than 200 miles—or 320 kilometers—to the east. Years later, both Esther (Esther 1:2) and Nehemiah (Nehemiah 1:1) lived in Susa and served in the palace there. It is thought that the events recorded in the book of Esther occurred from 522–486 BC and that Nehemiah was the cupbearer of Artaxerxes around 446–445 BC.The citadel Daniel sees in Susa would have been a fortified castle. This was initially built by Darius and expanded by later kings. The city of Susa was in "Elam:" the ancient name for Persia. It was a highlands region and Persia's most important province. The Elamites were descendants of Elam, oldest son of Shem (Genesis 10:22). Daniel saw himself at the Ulai canal. This canal flowed beside Susa and merged with other streams to form a lake.
Another prophet, Ezekiel, also received visions beside a canal: the Chebar (Ezekiel 1:1).
