I will behave myself wisely in a perfect way I will manage my affairs with wisdom and integrity; which are the two chief qualifications requisite for all men, and peculiarly necessary in princes, whose example is wont to have great influence on the morals of their people, and who can with no dignity nor consistency punish the crimes of others, if they be guilty of the same crimes themselves. O, when wilt thou come to me?
And be with me to assist me to execute this my purpose. God is often said, in Scripture, to come to men when he fulfils a promise to them, confers a favour upon them, peculiarly assists them, or is, in an especial manner, present with them. David, having declared it to be his resolution to set his court and kingdom an example of true wisdom and unshaken integrity, shows, in these words, the sense he had of his need of a peculiar visitation of divine grace, to enable him to put his resolution in practice, and accordingly expresses the passionate desire which he had for it in these words. I will walk within my house I will conduct myself in my family and court, as well as in my public administration of the affairs of my kingdom, with a perfect heart Sincerely intending and desiring to please and glorify God, and to set before the members of my family, and all my subjects, an example worthy of their imitation. This clause adds weight to the former. He determines not only to walk in a perfect or right way, which a man might do for politic reasons, or with an evil design; but to do so with an upright, honest heart, which is most acceptable to God.
