We already studied the prophecies of Daniel two, seven and Revelation 12 and 13. But we must go on and finish the major prophecies of the Bible. There are so many opinions and false teachings that are leading people astray. Truth sets us free. We must always study for truth.
In Daniel 9, Daniel is praying to the covenant-keeping God. God had foretold through Jeremiah that at the end of 70 years in captivity, God would release the Jews back to Jerusalem. Daniel is praying to God to keep His covenant, even though the people were not worthy.
As he was praying, the angel Gabriel came to help Daniel understand an earlier vision. This vision was given to Daniel in the third year of King Belshazzar’s reign. It stated that "It will take 2,300 evenings and mornings; then the sanctuary will be reconsecrated".. Daniel 8:14. The actual translation for the word used as "reconsecrated" is "cleansed".
