54 So Moses and Eleazar the priest accepted the gifts from the generals and captains and brought the gold to the Tabernacle as a reminder to the Lord that the people of Israel belong to him.

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.
