Matthew Poole's Commentary
O praise the LORD, all ye nations: praise him, all ye people.THE ARGUMENT
This Psalm contains a prophecy of the calling of the Gentiles, as appears both from the matter of it, and from Romans 15:11, where it is quoted to that purpose.
An exhortation to all nations to praise God for his mercy and truth’s sake.
Acknowledge the true God, and serve him only, and cast away all your idols.
For his merciful kindness is great toward us: and the truth of the LORD endureth for ever. Praise ye the LORD.Toward us; either,
1. Towards us Jews, to whom he hath given those peculiar privileges which he hath denied to all other nations. But this may seem an improper argument to move the Gentiles to praise God for his mercies to others from which they were excluded. Or,
2. Towards all of us, all the children of Abraham, whether carnal or spiritual, who were to be incorporated together, and made one body and one fold by and under the Messias, John 10:16 Ephesians 2:14, which mystery seems to be insinuated by this manner of expression.
