An evil [man] seeketh only rebellion
For he seeks nothing but what is evil; and all sin is rebellion against God, a contempt of his laws, and a transgression of them; a trampling upon his legislative power and authority; an act of hostility against him, and a casting off allegiance to him. Or rather the words may be rendered, "rebellion", that is, "the rebellious man", so the Targum, the abstract for the concrete, "verily" or "only seeketh evil" F13; a man that is rebellious against his prince, that is of a rebellious disposition, is continually seeking to do mischief in the commonwealth; he is continually plotting and contriving destructive schemes, and stirring up sedition, and causing trouble; and so a rebel against God is always seeking that which is sinful, which is evil in its own nature, and contrary to the law and will of God; and in the issue brings the evil of punishment on himself; therefore a cruel messenger shall be sent against him:
if a rebel against his lawful sovereign, a messenger shall be sent by him to take him into custody, who will show him no mercy; or an executioner to dispatch him, who will not spare to perform his orders: and if a rebel against God, some judgment of God shall fall upon him in a very severe manner; or his own conscience shall accuse him, and shall be filled with dreadful apprehensions of divine vengeance; or Satan, the angel of death, shall be let loose upon him, to terrify or destroy him; or death itself, which spares none. The Septuagint and Arabic versions ascribe this to God as his act, rendering it, "the Lord shall send" and so Aben Ezra; who also refers the former clause to him, and gives it as the sense of it; that he shall seek to do the rebellious man evil, inflict on him the evil of punishment for the evil of sin.
