Psalms 101:7

7He who worketh deceit shall not dwell in the midst of my house This verse may be explained of all magistrates to whose charge the exercise of public judgments is committed, as well as of household servants. But as David has just now spoken in general of all officers, he seems now to speak properly of those who are near the person of the king. When the chief counsellors of kings and other intimate acquaintances who have gained possession of their ears, are deceitful and crafty, this becomes the source of all corruptions; for by their example they encourage others in evil, lifting up as it were the banner of licentiousness. And it is impossible that he who does not maintain good order in his own house, can be a fit person for holding the government of a whole realm. The authority which cannot preserve its influence under the domestic roof is of little worth in state affairs.
