JAS 5:3

3 Your gold and silver hath rusted, and the rust of them shall be to you into witnessing, and shall eat your fleshes, as fire. Ye have treasured to you wrath in the last days. (Your gold and silver have rusted, and their rust shall be the testimony against you, and shall eat your flesh, like fire. Ye have piled up wealth for yourselves in the Last Days.)
