1 [A Psalm of David.] I will sing of mercy and judgment. To you, O LORD, I will sing.
2 I will behave myself wisely in a perfect way. O when will you come to me? I will walk within my house with a perfect heart.
3 I will set no wicked thing before my eyes. I hate the work of those who turn aside. It shall not cleave to me.
4 A perverse heart shall depart from me. I will not know a wicked person.
5 Whoever secretly slanders his neighbor, I will cut him off. Him who has a high look and a proud heart, I will not endure.
6 My eyes shall be upon the faithful of the land so that they may dwell with me. He who walks in a perfect way, he shall serve me.
7 He who works deceit shall not dwell within my house. He who tells lies shall not remain in my sight.
8 Early I will destroy all the wicked of the land so that I may cut off all who practice wickedness from the city of the LORD.
John Calvin's Chapter Summary:
David was not as yet put in possession of the kingdom, but having been already created king by the appointment of God, he prepares himself for exercising the government in the best manner. And he not only stirs up himself to perform faithfully the duties of his kingly office by devoutly meditating on this subject, but also engages by a solemn vow to be God's faithful servant, in order to induce Him to put him speedily in possession of the kingdom.
