And they burned the city and all that [was] in it with fire; they put only the silver and gold, and the items of copper and iron, [into] the treasury of the house of Yahweh.

as Moses Yahweh's servant commanded the {Israelites}, as [it is] written in the scroll of the law of Moses: "an altar of unhewn stones [on] which no one has {wielded} an iron implement." And they offered burnt offerings on it and sacrificed fellowship offerings.

And the descendants of Joseph said, "The hill country is not enough for us, and all of the Canaanites living in the land of the valley [have] chariots of iron, those in Beth-shean and its villages, and those in the Jezreel Valley."

[the] hill country will be yours. Even though it [is] a forest, you will clear it, and it will be yours [to] its farthest borders. You will drive out the Canaanites, even though they have iron chariots and [are] strong."

he said to them, "Return to your tents with much wealth, and with very much livestock, with silver, gold, copper, iron, and with very much clothing; divide the war-booty of your enemies with your kinsmen."
