. . . all come from the same word: diaballo.
Corruption (moral and physical decomposition) is what it's called in the Scriptures. In today's vernacular we call it decay. It's when things rot. In Greek it comes from the word "diaballo".
The word "slander" and the word "devil" also come from the same word in Greek: "diaballo".
All of those things: decay, slander, and the devil are inseparable and came in at the same time, at the Fall. Redemption from decay, slander, and the devil was provided by the Father in Christ.
