“These garments showed that those who wore them were not ordinary Israelites, but Israelites who had been ‘set apart’ from the rest of the people (v. 1) to serve as priests.” (W. H. Grispen, Exodus, p. 263).
“The robe was then the garment that reminded both the high priest and (humanly speaking) the Lord of the glory, the exaltedness, and the sacredness of the office. . . . The bells drew attention to his sacred garments, the pomegranates reminded the high priest of the commandments (cf. also Num. 15:37-41), which he was to keep as well. As to the fulfillment of the high priestly office, we must note that as our High Priest Christ pleased the Lord both in His person and in His office.” (W. H. Grispen, Exodus, p. 271).
“Although the clothing of [Revelation 1] v 13 could also resemble kingly attire, its use here evokes the image of a priest because of the clear temple atmosphere of the ‘lampstands’ and the angels coming out of the heavenly temple, who wear the same clothing in 15:5-8. The ambiguity may be deliberate: perhaps both a king and a priest are in mind. . . . Christ’s sovereign oversight of the churches presupposes his constant presence among them.” (G. K. Beale, The Book of Revelation, p. 209).
