I looked and behold, the Temple of the Tabernacle of the Testimony in heaven was opened.
And the seven angels came out of the temple clothed in pure and white linen and having their breasts girded with golden girdles, having the seven plagues.
And one of the four living creatures gave the seven angels seven golden vials full of the wrath of God who lives forever and ever.
And the temple was filled with smoke from the glory of God and from His power and no man was able to enter into the temple until the seven plagues of the seven angels were fulfilled. Rev.15:5-8
Bless Jehovah you His angels that excel in strength, that do His commandments and hearkening unto His word. Bless Jehovah all you His hosts, you ministers of His that do His pleasure. Ps:103:20-21
Are they not all ministering Spirits sent forth to minister for them who shall be heirs of salvation? Heb 1:14
