3 Bible Verses about God Swearing Harm

As I swore in My anger, they shall not be admitted to My rest" --

And to whom did He swear that they should not be admitted to His rest, if it was not to those who were disobedient?

We who have believed are soon to be admitted to the true rest; as He has said, "As I swore in My anger, they shall not be admitted to My rest," although God's works had been going on ever since the creation of the world.
