“Devil” means slanderer

Devil: The name describes Satan as slandering God to man and man to God. The former work is of course, a part of his great work of temptation to evil and is not only exemplified but illustrated as to its general nature and tendency by the narrative of Gen. 3. The other work, the slandering or accusing men before God, is the imputation of selfish motives, (Job 1:9,10) and its refutation is placed in the self-sacrifice of those "who loved not their own lives unto death." [SATAN; DEMON]
