Adam Clarke's Bible Commentary Verse 3. The Lord is good ] Here is the first reason why he should be praised; and a second is subjoined: - For it is pleasant. - It is becoming to acknowledge this infinite Being, and our dependence on him; and it is truly comfortable to an upright mind to be thus employed.
Matthew Henry Commentary
Verses 1-4 - The subject-matter of praise, is the blessings of grace flowing from the everlasting love of God. The name of God as a covenant God an Father in Christ, blessing us with all spiritual blessings in him, is to be loved and praised. The Lord chose a people to himself, that the might be unto him for a name and a praise. If they do not praise his for this distinguishing favour, they are the most unworthy an ungrateful of all people.
