O sing unto the LORD a new song: sing unto the LORD, all the earth.
Ver. 1. O sing unto the Lord a new song] For this new mercy of the ark now brought into Jerusalem from the house of Obededom, 1 Chronicles 15:25, but especially of Christ, typified by the ark, who should be preached unto the Gentiles, believed on in the world, received up to glory, 1 Timothy 3:16 .
Sing unto the Lord, all the earth] Which they could not do aright till they had heard, believed, and were sealed, Ephesians 1:13. Unbelievers can have no true notion of God but as of an enemy; and, therefore, all their verbal praises are but a black sanctus, suitable to such saints.
