Albert Barnes Commentary Exodus 38:29

"And the brass of the offering was seventy talents, and two thousand and four hundred shekels." — Exodus 38:29 (ASV)

The value of the gold, if pure, in our money would be 175,075 British pounds, 13 shillings, and of the silver, 38,034 British pounds, 15 shillings 10d. These quantities of the precious metals come quite within the limits of probability, if we consider the condition of the Israelites when they left Egypt (see the note on Exodus 25:3), and the object for which the collection was made. Many have remarked that the quantities collected for the tabernacle are insignificant when compared with the hoards of gold and silver collected in the East in recent times, as well as in ancient times.
