Revelation 22:7  NASB

"Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor's crown. Whoever has ears, let them hear what the Spirit says to the churches. The one who is victorious will not be hurt at all by the second death."

the devil will put some of you in prison to test you

Then compare our appearance with that of the young men who eat the royal food, and treat your servants in accordance with what you see."

Be faithful

Whoever has ears, let them hear
