Isaiah 65:15-16

The reputation (name) of the rebellious Israelites would remain as a curse to all the Israelites, and Sovereign Yahweh would slay them. This is not a replacement of all Israel by the church, but a replacement of all who depended on formal worship for their relationship with God by those who genuinely loved and obeyed God. But those who faithfully served the Lord by keeping His covenant would have another reputation, namely, the reputation of the God of truth (lit. amen). People would bless and swear by this God, whom the "godly" served. Their godly conduct would testify to their solidarity with Him. In contrast to those whom He would slay (Isaiah 65:15), the faithful would be those whom He had forgiven.
