Adam Clarke on Psalms 37:23

The steps of a good man are ordered by the Lord - There is nothing for good in the text. גבר geber is the original word, and it properly signifies a strong man, a conqueror or hero; and it appears to be used here to show, that even the most powerful must be supported by the Lord, otherwise their strength and courage will be of little avail.

And he delighteth in his way - When his steps are ordered by the Lord, he delighteth in his way, because it is that into which his own good Spirit has directed him. Or, the man delights in God's way - in the law and testimonies of his Maker.
