Joshua 6:18

And ye, in any wise, by all means, keep yourselves from the accursed thing, lest ye make yourselves accursed, become polluted with the curse which God had pronounced upon the city and all it contained, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it, since the transgression of a single person would be charged to the entire people. "A devoted thing, Numbers 21:2; Deuteronomy 7:2; Deuteronomy 20:17, was that which had been doomed to the Lord, which no man might employ for his own use, but which was either put away and destroyed utterly to the honor of God, as the men and beasts in this passage, a propitiation, as it were, to the divine justice, that this might be glorified; or it was consecrated to the special service of God, as here all precious and useful metals. " (Starke.)
