A Psalm of David.

1I will sing of mercy and justice; unto You, O LORD, will I sing. 2I will endeavor to lead a blameless life - when will You come to help me? I will conduct the affairs within my house with a pure heart. 3I will not allow wicked things before my eyes. I hate perverted behavior; it shall have no appeal for me. 4I will not tolerate a wicked or perverse person in my presence. 5Nor will I tolerate anyone who disparages his neighbor, or has a haughty or prideful attitude. 6My focus shall be upon the faithful of the land, that they may associate with me; only those that act with integrity shall serve me. 7He that practices deceit shall not live within my house; those that lie shall not remain in my presence. 8I will promptly banish all the wicked from the land, and rid the city of the LORD of all wicked doers.
