Satan

(adversary). In O. T. a common noun, meaning enemy or adversary in general (1 Sam. 29:44And the princes of the Philistines were wroth with him; and the princes of the Philistines said unto him, Make this fellow return, that he may go again to his place which thou hast appointed him, and let him not go down with us to battle, lest in the battle he be an adversary to us: for wherewith should he reconcile himself unto his master? should it not be with the heads of these men? (1 Samuel 29:4); 2 Sam. 19:2222And David said, What have I to do with you, ye sons of Zeruiah, that ye should this day be adversaries unto me? shall there any man be put to death this day in Israel? for do not I know that I am this day king over Israel? (2 Samuel 19:22)); except in Job 1:6,12; 2:16Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them. (Job 1:6)
12And the Lord said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the Lord. (Job 1:12)
1Again there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them to present himself before the Lord. (Job 2:1); Zech. 3:11And he showed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him. (Zechariah 3:1), where the word becomes a proper noun, and spiritual representative of evil. In N. T. sense, chief of the evil spirits; great adversary of man; the devil (Matt. 4:10; 25:4110Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. (Matthew 4:10)
41Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: (Matthew 25:41); Rev. 20), and elsewhere. Called also “the prince of this world;” “the wicked one;” “the tempter;” and in Rev. 12:99And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. (Revelation 12:9), the old serpent, the devil, and Satan.
