Psalms 101:2

I will behave myself wisely - God's law prescribes a perfect way of life; in this perfect way I have professed to walk, and I must act wisely in order to walk in it.

When wilt thou come unto me? - I can neither walk in this way, nor grow wise unto salvation, unless thou come unto me by thy grace and Spirit; for without thee I can do nothing.

I will walk within my house - It is easier for most men to walk with a perfect heart in the Church, or even in the world, than in their own families. How many are as meek as lambs among others, when at home they are wasps or tigers! The man who, in the midst of family provocations, maintains a Christian character, being meek, gentle, and long-suffering to his wife, his children, and his servants, has got a perfect heart, and adorns the doctrine of God his Savior in all things.

The original is very emphatic; אתהלך ethhallech, "I will set myself to walk," I will make it a determined point thus to walk. I will bear and forbear with children, servants, etc., not speaking rashly, nor giving way to bad tempers. Through various motives a man will behave with propriety and decorum among others; but none of these motives operate in his own house where he feels himself master, and consequently under no restraint.

I will behave myself wisely - In the choice of principles to guide me; in my conduct in my family; in my official relations. This expresses a "desire" to act wisely, and a "purpose" to do it.

In a perfect way - In accordance with the perfect rules of right. I will make these my guide. I will "aim" to be perfect; I will have before me a perfect standard.

O when wilt thou come unto me? - Perhaps this would be better rendered, "When thou dost come unto me;" that is, When then dost visit me and my dwelling, thou shalt find that these are the principles which regulate and govern me in my house. The idea is that God would come to visit his habitation, and inspect his conduct; and that whenever this should occur, however often it might be, or however unexpectedly he might come, he should "always" find these principles governing him in his family. A man should so live that "whenever" God comes into his dwelling, or when anyone comes, or however narrow and searching may be the inspection, these principles shal be found to regulate his conduct.

I will walk within my house - Before my family; in the principles which shall govern me there.

With a perfect heart - Always aiming to do exactly that which is right: in my general conduct; in the rules by which I live; in my treatment of all under my charge and in my employ. The great principles of "right," in everything - in the smallest matters - shall guide and govern me.

101:2 I will - I will manage all my affairs with wisdom and integrity. When - God is often said in scripture to come to men, when he fulfills a promise to them. House - In my court and family, as well as in my public administrations.
