Praise ye the Lord - This, which is a sort of title, is wanting in several MSS., and in the Syriac Version.

O give thanks unto the Lord; for he is good - Ye who live by his bounty should praise his mercy. God is the good Being, and of all kinds of good he is the Author and Dispenser. That the term God among our Anglo-Saxon ancestors, expressed both the Supreme Being and good or goodness, is evident from the Anglo-Saxon version of this clause: "Confess Lord for that God, (or good), for that on world mildheartness his." Which the old Psalter thus translates and paraphrases: -

Trans. Schifes to Lorde for he is gude; for in worlde the mercy of him.

Par - Schryfes synes, and louyngs to God. for he is gude of kynde, that nane do bot aske his mercy; for it lastes to the worlds ende in wriches whame it comfortes and delyvers: and the blysfulhede that is gyfen thrugh mercy is endles. That is: -

Confess your sins, and give praise to God, for he is good in his nature to all that ask his mercy; for it lasts to the world's end in comforting and delivering the wretched: and the blessedness that is given through mercy is endless.

As part of the preceding Psalm is found in

1 Chronicles ch.

Psalm 106:16 They envied Moses also in the camp, and Aaron the saint of the LORD.

, so the first and two last verses of this are found in the same place; and it is highly probable this was composed upon the same occasion as the former, to which it seems to be a continuation; for as that celebrates the mercies of God to Israel, so this confesses and deplores the rebellions of Israel against Jehovah.

Sin: Its Spring-Head, Stream, and Sea
It may help us to escape out of the meshes of our natural depravity, if we look back and see the causes of our fathers' sins. To confess our personal sin will tend to keep us humble; and in view of the Lord's mercy, which has spared and pardoned us, a sense of our guilt will make us grateful. The less we think of ourselves the more we shall think of him whose "mercy endureth for ever"; and if we see where our fathers' sins began, and how they grew, and what they came to, we may hope that the Spirit …

Rest for the Weary
Come unto me, all ye that labour and are heavy laden, and I will give you rest. W hich shall we admire most -- the majesty, or the grace, conspicuous in this invitation? How soon would the greatest earthly monarch be impoverished, and his treasures utterly exhausted, if all, that are poor and miserable, had encouragement to apply freely to him, with a promise of relief, fully answerable to their wants and wishes! But the riches of Christ are unsearchable and inexhaustible. If millions and millions …
