Matthew Henry Commentary Psalms 135:1-4

"Praise ye Jehovah. Praise ye the name of Jehovah; Praise [him], O ye servants of Jehovah, Ye that stand in the house of Jehovah, In the courts of the house of our God. Praise ye Jehovah; for Jehovah is good: Sing praises unto his name; for it is pleasant. For Jehovah hath chosen Jacob unto himself, [And] Israel for his own possession." — Psalms 135:1-4 (ASV)

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 and Father in Christ, blessing us with all spiritual blessings in Him, is to be loved and praised. The Lord chose a people for Himself, so that they might be to Him for a name and for praise. If they do not praise Him for this distinguishing favor, they are the most unworthy and ungrateful of all people.
