Exodus 31:10

‎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. בגדי השרד GARMENTS OF SERVICE — Some explain שרד to mean work and service (cf. שרת to serve), as the Targum renders it: לבושי שמושא, “garments for the service”. There is, however, no other example of it (of שרד) in Scriptures. I, however, think that it is an Aramaic expression, like the Targum of קלעים, hangings, which Onkelos renders by שרדין, and of מכבר, “grate”, which he renders by שרדא, both words denoting net-work, and they are called “garments of שרד, net-work”, because they were woven not in the ordinary way but with the needle (a kind of crochet-work), made with many holes; “lacies” in old French; English, net or mesh-work.
