John Trapp on Isaiah 49:8

Ver. 8. In an acceptable time] Heb. In a time of my good pleaſure, or goodwill, i. e. when of free grace I am pleaſed to ſend thee into the world, and to cauſe the Goſpel to be preached all abroad: thereby declaring my ſelf fully appeaſed which the men of my good will, as the Elect are called, Luk. 2.14. Confer 2 Cor. 6.2.

Have I heard thee] Or, will I hear thee, ſc. interceding, and will I help thee, ſc. conflicting.

And give thee for a Covenant] i. e. For a Mediatour of the New Covenant, which is ratified by thy blood: as was ſignified by the book ſprinkled with the blood of the ſlain ſacrifice.

To eſtabliſh the earth] Had not Chriſt undertook the ſhattered condition of the world to uphold it, it had faln about Adams cares.

To cauſe to inherit the deſolate heritages.] i. e. Heaven forfeited by us in our firſt Parents: or, as others, the Countries of the Nations now converted.
