Joshua 6:18 - Joseph Benson’s Commentary on the Old and New Testaments

Keep yourselves from the accursed thing It should rather be rendered, the devoted thing, meaning the spoils devoted to the Lord. These they were not to touch, on pain of being themselves devoted to death. Lest ye make yourselves accursed Lest you draw upon yourselves the immediate curse of God, and so bring yourselves under the same sentence of destruction as the inhabitants and things of Jericho are under. And make the camp of Israel a curse By provoking God to punish them for your sin, in which they may be one way or other involved; for the whole camp having sins of their own, God might take what occasion he saw fit to inflict this punishment.
