Malaquias 3

6 For I am the Lord, I don’t change, and you haven’t stopped being descendants of Jacob.*3:6. There is debate over the meaning of this second part of the verse. It could be interpreted that it is because of God’s unchanging nature that the descendants of Jacob have not been destroyed. However, in context it seems more likely that God is saying "I haven’t changed, and you haven’t changed either—you are just like your forefather Jacob who was a deceiver too…" The word used can mean either "ended as in destroyed," or simply "stopped."
