Please do look at the context in Daniel 9 verse 1&2 Daniel understood from the scriptures given to Jeremiah the prophet that the desolution would last 70 years, from verse 4 to 19 Daniel is praying to the lord saying how they have rebelled and turned away from the lord . Verse 20 while Daniel was still in prayer Gabriel comes to give Daniel insight and understandind. In the context of all of this Gabriel declairs as soon as you started to pray an answer was given which I have come to tell you Seven times seventy are decreed for your people and youre holy city to finish transgression, to put an end to sin , to atone for wickedness.
Thirdwitness please read the context the day year rule is only required if you come to this with preconceived idears.
As I said before the SDAs would like to prove the day year rule as it would validate their other prophecys such as 1844. If you can solve the day year rule you could be of great service to them but you would have to do it in a scholarly way. Im an SDA who cant beleive the day year rule because its not in the bible. Its not found in any good bible commentarys either
I wait eagerly for youre answer but I wont hold my breath.
