ISB ~ Revelation 1 v13

long robe:A vestment worn by a high priest (Ex 28:4; Sir 45:8). Similar attire is worn by the heavenly angels (Rev 15:6). Jesus ministers to the needs of the seven Churches just as the Temple priests tended the menorah lamps by trimming their wicks and replenishing their oil (Ex 27:20-21) (CCC 662).
