The following verse speak about the New Covenant and the part which the houses of Judah and Israel will play in bringing the Gentiles to salvation:
"Give ear and come to me; hear me, that your soul may live. I will make an everlasting covenant with you...Surely you will summon nations you know not, and nations that do not know you will hasten to you, because of the Lord your God, the Holy One of Israel, for he has endowed you with splendor" (Isa.55:3,5; NIV).
