The Norm of Life for Rulers
A psalm for David himself. Mercy and judgment I will sing to thee, O Lord: I will sing,  And I will understand in the unspotted way, when thou shalt come to me. I walked in the innocence of my heart, in the midst of my house.  I did not set before my eyes any unjust thing: I hated the workers of iniquities. The perverse heart did not cleave to me: and the malignant, that turned aside from me, I would not know.  The man that in private detracted his neighbour, him did I persecute. With him that had a proud eye, and an unsatiable heart, I would not eat.
 "I will understand"... That is, I will apply my mind, I will do my endeavour, to know and to follow the perfect way of thy commandments: not trusting to my own strength, but relying on thy coming to me by thy grace.
 My eyes were upon the faithful of the earth, to sit with me: the man that walked in the perfect way, he served me.  He that worketh pride shall not dwell in the midst of my house: he that speaketh unjust things did not prosper before my eyes.  In the morning I put to death all the wicked of the land: that I might cut off all the workers of iniquity from the city of the Lord.(Psalm 100)
