Matthew Poole and continuators on Psalms 101:2

2 I will behave my self wisely in a perfect way ; O when wilt thou come unto me ! I will walk within my house with a perfect heart .

I will manage all my affairs with wisdom and integrity; which are the two chief qualifications requisite for all men, Mat. 10. 16. and most necessary in Princes.

O when wilt thou give me the Kingdom which thou hast promised me, that so I may be capable of executing these good purposes both for my own comfort and for the benefit of thy people? Or, without an interrogation, as this Particle is used, Exod. 20. 24. when thou shalt come to me, to wit, in the performance of that promise to me. He speaks not exclusively, as if he would not walk wisely and righteously in the mean time, but emphatically, that he would continue to do so when he was advanced to the Kingdom, and that he would not suffer himself to be corrupted by his Royal Power and Dignity, as the Princes of the World commonly were. Withal he may intimate, that now he could not do as he desired, and that by the necessity of his affairs he was forced to make use of such men as he did not like, and to wink at those miscarriages, which it was not now in his power to reform. God is oft said in Scripture to come to men when he fulfils a promise to them, or confers a favour or blessing upon them, as Gen. 18. 10. Exod. 20. 24. Psal. 80. 2. Isa. 35. 4. &c.

In my own Court and Family, as well as in my publick administrations; knowing how great an influence the example of my private conversation will have upon my people either to reform or corrupt them.

This Clause adds weight to the former, I will not onely walk in a perfect or right way (which a man may do for politick reasons or with evil design, but I will do so) with an upright and honest heart, which is most acceptable to God.
