Commentary on Psalm 107:1

• John Calvin (Reformed), Calvin's Commentaries on Psalm 107:1-43: PSALM 107 The Psalmist teaches us, in the first place, that human affairs are not regulated by the fickle and uncertain wheel of fortune, but that we must observe the judgments of God in the different vicissitudes which occur in the world, and which men imagine happen by chance.
• C.H. Spurgeon (Reformed Baptist), The Treasury of David on Psalm 107:1: O give thanks unto the Lord, for he is good. It is all we can give him, and the least we can give; therefore let us diligently render to him our thanksgiving. The psalmist is in earnest in the exhortation, hence the use of the interjection "O", to intensity his words: let us be at all times thoroughly fervent in the praises of the Lord...
• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Psalm 107:1-9: Here is, I. A general call to all to give thanks to God, Psa 107:1. Let all that sing this psalm, or pray over it, set themselves herein to give thanks to the Lord; and those that have not any special matter for praise may furnish themselves with matter enough from God's universal goodness.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Psalm 107:1: O give thanks unto the Lord,.... As all men should do, at all times and for all things; the psalm begins as the former does, and gives the same reasons for thanksgiving. For he is good; and does good, and is the author of all good. For his mercy endureth for ever; and men in every age are partakers of it.
