The steps of a good man are ordered by the Lord; rather, established; i.e. upheld, and made firm. It is not the general superintendence of men's steps and goings by God (Proverbs 16:9; Proverbs 20:24) which is here spoken of; but the special strengthening and supporting of the steps of the pious.
The wont גבר must be understood, not of the ordinary man, but of the good man. (" גבר, viri, scilicet justi, et Jova benedicti," Roseumuller). And he delighteth in his way. He "knows" it (Psalms 1:6), and looks upon it with favour, and even "has pleasure" in it (Psalms 35:27).
