Psalms 101:2 - Exposition

I will behave myself wisely in a perfect way (comp. Psalms 18:22 ; Isaiah 26:7 ). The psalmist aspires after "perfectness." Then feeling his inability to walk in the perfect way by his own strength, he cries to God for aid— O when wilt thou come unto me? "Unless," i.e; "thou come unto me, I cannot keep one of these resolutions. O Lord, come quickly." I will walk within my house with a perfect heart. It is not only the "way," or conduct, that requires to be "perfect," but the "heart" also, or the motives from which the conduct springs.
