Psalms 101:4 - Matthew Poole's English Annotations on the Holy Bible

A froward heart; a man of a corrupt mind and wicked life, such as other princes choose and prefer, as being suitable to themselves, and to their wicked designs. Shall depart from me; shall be turned out of my court, lest they should tempt me, or infect the rest of my family, or be injurious or scandalous to my people. I will not know, i.e. not own nor countenance.
