Jas 5:3. "The rust (ios) of your riches shall be a witness against you" in the judgment, that your riches were of no profit, lying unemployed, and so contracting rust. Mt 6:19-20, "rust" (brosis), "corrosion."
"Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal. "But store up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in or steal;
Your gold and your silver have rusted; and their rust will be a witness against you and will consume your flesh like fire. It is in the last days that you have stored up your treasure!
