Exodus 38:25 - Ellicott's Commentary On The Whole Bible

The silver... was an hundred talents. — The silver talent contained 3,000 shekels, as all allow, and as appears from the present passage. If the “shekel of the sanctuary” weighed, as is generally supposed, about 220 grains troy, the value of the silver contributed would have been £40,000, or a little under. It was contributed by “them that were numbered of the congregation,” each of whom paid a bekah, or half a shekel. (See above, Exodus 30:12-16.)
