Rashi
ואת בגדי השרד AND THE GARMENTS OF THE SERVICE — I think — according to the plain sense of the verse — that one cannot say that Scripture is here speaking of (referring to) the priestly garments, because to them refer the next words: “and the garments of holiness for Aaron the priest, and the garments of his sons to minister as priests”. But these בגדי שרד are identical with the garments of blue purple wool, and red purple wool, and crimson wool which are mentioned in the chapter (Numbers IV.) giving an account of Israel’s encampments: (Numbers 4:12) “and they shall put them in a garment of blue purple”; (Numbers 4:13) “and spread a garment of red purple thereon”; (Numbers 4:8) “and they shall spread upon them a garment of crimson”. And indeed my opinion appears correct, because it is said, (Exodus 39:1) “And of the blue purple, and of the red purple, and of the crimson, they made garments of the service (בגדי שרד) to minister in the holiness”, and linen is not mentioned among them (these materials). Now if Scripture were speaking of the priestly garments it could not have omitted “linen”“, for we do not find in respect of even one of them (of the priestly garments) mention of red purple or crimson without linen.
Chizkuni
ואת בגדי השרד, “and the service vestments.” The word שרד is reminiscent of פליט ושריד in Jeremiah 44,14, where it refers to remnants of escapees after the destruction of the Temple. Here too, the expression is referring to excess materials used for weaving of the carpets forming the inner ceiling of the Tabernacle, and the priestly garments, as well as the curtain at the entrance of the Tabernacle and the dividing curtain between the Sanctuary and the Holy of Holies. From these remnants the covers for the furnishings of the Tabernacle while it was in transit were constructed. These covers were alluded to by the same expression in Exodus 39,41.
Da'at Zekenim
ואת בגדי השרד, “and the service garments;” according to Rashi these were not priestly garments, but garments woven alternately of blue wool and red wool, i.e. תכלת וארגמן as described in the portion dealing with the journeys of the Israelites (Numbers 4,7-9). This sounds quite unlikely, as these garments are referred to throughout the Talmud as priestly vestments.
