Charles Ellicott Commentary Isaiah 65:15

"And ye shall leave your name for a curse unto my chosen; and the Lord Jehovah will slay thee; and he will call his servants by another name:" — Isaiah 65:15 (ASV)

You shall leave your name for a curse ... —The phrase has parallels in Numbers 5:21; Zechariah 8:13; Jeremiah 29:22, the thought in each case being that the person named is under so heavy a penalty from the wrath of Jehovah that he becomes a representative instance of what that wrath can accomplish, and because the old name (for example, Jacob or Judah) has been thus identified with evil. He will call His chosen ones, the true Israel, by another name, which shall be for blessing and not for cursing. (Compare to Isaiah 62:2, Revelation 2:17, Revelation 3:12.)
