What does Daniel 8:1 mean?
Two years after his first vision (Daniel 7:1), Daniel received another prophecy. The first occurred in Belshazzar's first year as king (Daniel 5:1). The one reported here came to Daniel in Belshazzar's third year. Both visions occurred before the handwriting on the wall in Belshazzar's palace (Daniel 5:30–31).Daniel's writing began in Hebrew, switching to Aramaic in the middle of an early verse (Daniel 2:4). Aramaic was the commercial language spoken mainly in that region of the ancient Middle East. Here, at the start of chapter 8, the language returns to Hebrew. This difference is significant: the Aramaic portion deals primarily with the Gentiles; the Hebrew portion deals mainly with the Jews of the nation of Israel.
The military conflicts described in chapter 8 involve Palestine, with reference to daily sacrifices, the temple, and Israel's Messiah. The second vision came to Daniel while he was awake, whereas the first vision came to him while he was asleep and dreaming. Some Bible teachers estimate Daniel received this second vision in 551 BC.
