Daniel
Daniel 8:2ESV·traditional attribution

And I saw in the vision; and when I saw, I was in Susa the citadel, which is in the province of Elam. And I saw in the vision, and I was at the Ulai canal.

Without any doubt, the Prophet here recognized a new empire as about to arise, which could not happen without Babylon being reduced to slavery. Hence it would tend in. no slight degree to alleviate the cares of the pious, and to mitigate their sorrows, when they saw what they had previously thought incredible, namely, the approaching destruction of that horrible tyranny under which they had been so, cruelly oppressed.

Here is, I. The date of this vision, Dan 8:1. It was in the third year of the reign of Belshazzar, which proved to be his last year, as many reckon; so that this chapter also should be, in order of time, before the fifth.

And I saw in a vision,.... The following things: and it came to pass, when I saw, that I was at Shushan in the palace, which is in the province of Elam; not in reality, but so it seemed to him in the vision; as Ezekiel, when in Babylon, seemed in the visions of God to be at Jerusalem, Eze 8:3.
