It is a good thing to give thanks unto the LORD, and to sing praises unto your name, O most High:
Read Chapter 92
Augustine of Hippo
1. ...We are not Christians, except on account of a future life: let no one hope for present blessings, let no one promise himself the happiness of the world, because he is a Christian: but let him use the happiness he hath, as he may, in what manner he may, when he may, as far as he may. When it is present, let him give thanks for the consolation of God: when it is wanting, let him give thanks to the Divine justice. Let him always be grateful, never ungrateful: let him be grateful to his Father, who soothes and caresses him: and grateful to his Father when He chasteneth him with the scourge, and teacheth him: for He ever loveth, whether He caress or threaten: and let him say what ye have heard in the Psalm: "It is a good thing to give thanks unto the Lord; and to sing praises unto Thy Name, Thou Most Highest" (ver. 1).
2. This Psalm is entitled, a Psalm to be sung on the Sabbath day. Lo, this day is the Sabbath, which the Jews at this period observe by a kind of bodily rest, langui...
Day. The Jews say, that Adam sung this at his creation, (Chaldean) or that it refers to the reign of the Messias, which shall last one thousand years after this world is ended. (Kimchi)
Others think it is a thanksgiving after the defeat of Sennacherib, (Ven. Bede) or Absalom. (Ferrand)
It might be sung by the sons of Moses, who expected to be shortly delivered from Babylon, (Calmet) or by the people on the sabbath, (Berthier) though many of the Fathers think, that this word denotes "the repose of the life to come. "The occasion or author of this psalm cannot be clearly ascertained. (Calmet)
When we enjoy rest from labour, we ought particularly to praise God's works. (Worthington)
Praise. Literally, "to confess "(Haydock) as we must be free from sin before we can worthily proclaim God's praises. (Eusebius) (St. Jerome)
But here to confess means to praise, (Calmet) or give thanks. (Worthington)
