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.Ver. 1. Praise ye the Lord,.... Or, "hallelujah". This is properly the title of the psalm: Aben Ezra says it is a word of the psalmist; it shows that all that a good man is, has, or does, is from the Lord; and therefore his name is to be praised: and he is not only to be praised for his perfections and works, but for this among others, that there are any good men on earth that fear and serve him, and are useful in their day and generation.
Blessed is the man that feareth the Lord; not men, but the Lord; not his wrath, nor his judgments here or hereafter, but his goodness; not with a servile, but with a godly fear. This every man does not; there are but few that truly fear the Lord, only such who have the grace of God; and these are happy men: they have an interest in the heart of God, in his pity, love, and delight; great discoveries are made unto them; the secret of the Lord is with them; he shows them his covenant; and the sun of righteousness arises upon them: they are guarded and protected by the Lord; his eye of providence, as well as love, is upon them, and his angels encamp about them: they are supplied with all needful good things, temporal and spiritual; and have much goodness laid up for them hereafter.
This psalm begins with what the preceding ends, the fear of the Lord; and is a further illustration and enlargement of it; See Gill on "Ps 111:10".
