This psalm, also, very probably, was written by David, and is composed as the former, in an alphabetical order. The inscription of it in the Syriac version is,
``When David in it commanded Solomon his son, saying, Keep the commandments of, the Lord, and worship him: likewise the calling of the Gentiles and the righteousness of Christ.''
The subject matter of the psalm are the character, conduct, usefulness, and happiness of a good man.
