38:1-8 In all ages of the church there have been some persons more devoted to God, more constant in their attendance upon his ordinances, and more willing to part even with lawful things, for his sake, than others. Some women, devoted to God and zealous for the tabernacle worship, expressed zeal by parting with their mirrors, which were polished plates of brass. Before the invention of looking-glasses, these served the same purposes.
8. laver of brass … of the looking glasses of the women—The word mirrors should have been used, as those implements, usually round, inserted into a handle of wood, stone, or metal, were made of brass, silver, or bronze, highly polished [Wilkinson]. It was customary for the Egyptian women to carry mirrors with them to the temples; and whether by taking the looking glasses of the Hebrew women Moses designed to put it out of their power to follow a similar practice at the tabernacle, or whether the supply of brass from other sources in the camp was exhausted, it is interesting to learn how zealously and to a vast extent they surrendered those valued accompaniments of the female toilet.
of the women assembling … at the door—not priestesses but women of pious character and influence, who frequented the courts of the sacred building (Lu 2:37), and whose parting with their mirrors, like the cutting the hair of the Nazarites, was their renouncing the world for a season [Hengstenberg].
