He has the worst names – Thomas Brooks

We may read much of Satan’s nature and disposition by the diverse names and epithets that are given him in the Scripture. Sometimes he is called Behemoth, whereby the greatness and brutishness of the devil is figured (Job 40:15). Those evil spirits are sometimes called accusers, for their calumnies and slanders; and evil ones, for their malice. Satan is Adversarius, an adversary, that troubles and molests (1 Pet. 5:8). Abaddon is a destroyer (Rev. 9:11). They are . . .
tempters, for their suggestions;
lions, for their devouring;
dragons, for their cruelty;
serpents, for their subtlety.

As his names are, so is he. Satan’s names answer to his nature. He has the worst names and the worst nature of all created creatures.
