Isaiah 65:15

And ye shall leave your name for a curse unto my chosen,.... Execrable and abominable to them, as the name of a Jew is to this day, and in all places; for their unbelief and impenitence, for their perfidy and insincerity, for their tricking and covetousness, and other crimes they are addicted to; see Jeremiah 24:9:

for the Lord God shall slay them; by the sword of the Romans, and by his judgments, which continue upon them; the Targum says, with the second death; and so Jarchi interprets it of eternal death, which is the just wages of sin:

and call his servants by another name; a new name, as the Septuagint and Arabic versions; the name of the people of God, the Gentiles formerly were not called by; but now all that believe in Christ, whether Jews or Gentiles, are his people; the name of the sons of God, a name better than that of sons and daughters of the greatest potentate; the name which the mouth of the Lord calls, "Hephzibah" and "Beulah", being delighted in by the Lord, and married to him; or rather the name of Christians, first given to the disciples of Christ at Antioch, and ever since continued, Acts 11:26.
