“And still another angel [the fifth] emerged from the temple sanctuary that is in heaven, he, too, having a sharp sickle.

Revelation 14:17,

25. (a) What is indicated by the fact that the fifth angel came from the temple sanctuary? (b) Why is it fitting that the command to begin reaping comes from an angel who “emerged from the altar”?

²⁵ The fifth angel comes from Jehovah’s presence in the temple sanctuary; hence, the final harvest also takes place according to Jehovah’s will.
