Isaiah 65:15 - Matthew Poole's English Annotations on the Holy Bible

Your name shall rot, as Proverbs 10:7, or only be used when men would curse others, saying, Let them be made like such persons. As the names of Leah and Rachel, Ruth 4:11, and others of God's servants, were used in blessing; so your names shall only be used in cursing; or when men will curse themselves, they shall use your names as examples of the eminent wrath of God upon sinners. For you shall not perish by an ordinary hand, but by the hand of the Lord God; and as is the God, so is his justice, so is his strength; yea, God himself shall look upon your name as accursed, and not suffer his people to be called by it; they shall not be called Jews, but Christians, Acts 11:26, the children of God, 1 Thessalonians 1:12. So detestable a sin is idolatry, that God will not suffer himself to be called by a name given to idols, how proper soever it be to express his perfection, Hosea 2:16,17; nor yet suffer his own people to be called by a name by which idolaters are known.
