and the seven angels with the seven plagues emerged from the sanctuary, clothed with clean, bright linen and girded about their breasts with golden girdles.

Revelation 15:5-

15. Why is it not surprising that the seven angels emerge from the sanctuary?

¹⁵ As respects the Israelite temple, which contained representations of heavenly things, only the high priest could enter the Most Holy, here called “the sanctuary.” (Hebrews 9:3, 7) It represents the place of Jehovah’s presence in heaven. In heaven itself, however, not only does the High Priest Jesus Christ have the privilege of entering in before Jehovah but the angels do also. (Matthew 18:10; Hebrews 9:24-26) It is not surprising, then, that seven angels should be seen coming out from the sanctuary in heaven. They have a commission from Jehovah God himself: Pour out the bowls full of the anger of God.​—Revelation 16:1.

16. (a) What shows that the seven angels are well qualified for their work? (b) What indicates that others are involved in the great task of pouring out the symbolic bowls?

¹⁶ These angels are well qualified for this work. They are clothed with clean, bright linen, showing that they are spiritually clean and holy, righteous in Jehovah’s sight. Also, they wear golden girdles. Girdles are usually used when a person girds himself for a task to be accomplished. (Leviticus 8:7, 13; 1 Samuel 2:18; Luke 12:37; John 13:4, 5) So the angels are girded for carrying out an assignment. Moreover, their girdles are golden. In the ancient tabernacle, gold was used to represent divine, heavenly things. (Hebrews 9:4, 11, 12) That means that these angels have a precious, divine commission of service to perform.
