Of David. A psalm.

1I will sing of faithfulness and justice; I will chant a hymn to You, O LORD. 2I will study the way of the blameless; when shall I attain it? I will live without blame within my house. 3I will not set before my eyes anything base; I hate crooked dealing; I will have none of it. 4Perverse thoughts will be far from me; I will know nothing of evil. 5He who slanders his friend in secret I will destroy; I cannot endure the haughty and proud man. 6My eyes are on the trusty men of the land, to have them at my side. He who follows the way of the blameless shall be in my service. 7He who deals deceitfully shall not live in my house; he who speaks untruth shall not stand before my eyes. 8Each morning I will destroy all the wicked of the land, to rid the city of the LORD of all evildoers.
