54 Then Moses and Eleazar the priest took the gold given by the captains of thousands and captains of hundreds, and took it into the Tent of meeting, to be a sign in memory of the children of Israel before the Lord.

Matthew Henry's Commentary on Numbers 31:54

Commentary on Numbers 31:48-54

(Read Numbers 31:48-54)

The success of the Israelites had been very remarkable, so small a company overcoming such multitudes, but it was still more wonderful that not one was slain or missing. They presented the gold they found among the spoils, as an offering to the Lord. Thus they confessed, that instead of claiming a reward for their service, they needed forgiveness of much that had been amiss, and desired to be thankful for the preservation of their lives, which might justly have been taken away.
