Fear none of those things which you will suffer: behold, the devil shall cast some of you into prison, that you may be tried; and you shall have tribulation ten days: be faithful unto death, and I will give you a crown of life.
All Commentaries on Revelation 2:10 Go To Revelation 2
Bede
AD 735
ten days: He means the whole of the time during which the commandments of the decalogue are necessary. For as long as thou shalt follow the light of the divine word, thou must needs suffer imprisonment from the enemy who opposes thee. Some understand that the ten persecutions of the heathen, from the Emperor Nero to Domitian, are signified.
