Joshua 6:19

Ver. 19. But all the silver, and gold,—are consecrated unto the Lord— God requires, that all the silver, gold, brass, iron, and all other metal found in Jericho, should be consecrated to the use of his sanctuary, and carried into his tabernacle, to supply the wants of that sacred house; but, doubtless, first to be purified by passing through the fire, according to the law, Numbers 31:22 and excepting the idols, which were to be absolutely destroyed.

Deuteronomy 7:25. The Jews say, that all these riches belonged to God, inasmuch as Jericho was taken on a sabbath-day; but, as we before remarked, God required them as a tribute and homage, by which the Israelites acknowledged that to his power and goodness they owed the victory which now opened to them the entrance and possession of the country.
