The End Times
The whole chapter is a prophesy of the end times.
v1: Archangel Michael is assigned to protect the Jews during the tribulation period (10:13,21;Rev 12:7).
v1: […a time of distress..] referring to when antichrist broke his covenant with the Jews in the middle of the seven years covenant. Greatest prosecutions to the Jews will happen during this time.
v2 talks about resurrection.
OT saints believed in resurrection (Gen 22; Heb 11:19; Ps 17:!5; 49:15; 71:20; Is 25:7; Hosea 13:14)
Please read 1 Corinthians 15 for fuller understanding of the resurrection body.
It seems that this verse suggests the believers and non believers will be resurrected at the same time, the believers will receive everlasting life, the non believers will receive punishment.
Many Christians believe that non believers will be judge after the millenium kingdom, on the great while throne judgement mentioned in Rev 20:11-15.
v3: [..Those who are wise..] is this referring to the over comers?
Seal the Words
v4, v9: This prophesy is sealed until the time of the end, possibly referring to the finish of the book of Revelation. [..Do not seal up the words of the prophecy of this book, because the time is near..]
A time, times and half a time (v5-7)
antichrist will broke his covenant with Jews in the middle of the seven years covenant, which is three and half years into the covenant. (11:27).
v10: [..many will be purified, made spotless and refined…] many Jews will believe in Christ during the Great Tribulation. The truly saved develop in godliness through trials. The unsaved pursue false values.
1290 days and 1335 days
1290 days is referring to 30 days after the end of seven years tribulation.
1335 days is referring to 45 days after the 1290 days. Possibly referring to the Judgement Seat of Christ (2 Cor 5:10). [..blessed is the one who waits for and reaches the end..] possibly referring to the rewards will be given to over comers on the Judgement Seat of Christ.
