Isaiah 65:15 - Ellicott's Commentary On The Whole Bible

Ye 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, say of Jacob or of Judah, has been thus identified with evil. He will call His chosen ones, the true Israel, as by another name, which shall be for blessing, and not for cursing. (Comp. Isaiah 62:2; Revelation 2:17; Revelation 3:12.)
