Solomon
Proverbs 17:11ESV·traditional attribution

An evil man seeks only rebellion, and a cruel messenger will be sent against him.

Matthew Henry Presbyterian @wholebiblehenry

Here is the sin and punishment of an evil man. 1. His sin. He is an evil man indeed that seeks all occasions to rebel against God, and the government God has set over him, and to contradict and quarrel with those about him. Quaerit jurgia - He picks quarrels; so some.

John Gill Reformed Baptist @doctorgill

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.

Jamieson-Fausset-Brown Reformed @jfbcommentary

Such meet just retribution (Kg1 2:25). a cruel messenger--one to inflict it.
