Hold him not guiltless - i. e. “Do not treat him as an innocent man. Punish him as in thy wisdom thou deemest best. Not capitally at once; but so that he may be likely to give thee in course of time a just occasion to slay him.” So, at least, Solomon seems to have understood the charge. (See 1 Kings 2:36-46.)
