Adam Clarke on Joshua 6:24

Only the silver, and the gold - they put into the treasury, etc. - The people were to have no share of the spoils, because they had no hand in the conquest. God alone overthrew the city; and into his treasury only the spoils were brought. This is one proof that the agitation of the air, by the sound of the people's voice, was not the cause of the fall of the city walls.

Vessels of brass and of iron - Instead of כלי keley, Vessels, the Septuagint, in the Alexandrian copy, evidently have read כל col, All, with the omission of the י yod; for in Jos 6:19 they translate πας χαλκος και σιδηρος, All the brass and iron: but this reading does not appear in any of Kennicott's or De Rossi's MSS.
