Isaiah 55:5 - Exposition

Thou shalt call a nation that thou knowest not (comp. Psalms 18:43 ). The object of address in this verse appears to be the Messiah. He, at his coming, will "call" into his kingdom "a nation," or rather, "people," with whom he has had no covenant hitherto; and they will readily and gladly obey the call. Thus God's kingdom will be enlarged, and Israel's glory will be increased , Because of the Lord … for he hath glorified thee . The great cause of the attraction will be the "glory" which God the Father has bestowed upon his Son, by raising him from the dead, and exalting him to a seat at his right hand in heaven ( Acts 2:32-35 ; Acts 3:13-15 ).
