'Cancel' in the Bible

We will not buy on the Sabbath or on a holy day from the neighboring peoples who bring their wares and all kinds of grain to sell on the Sabbath day. We will let the fields lie fallow every seventh year, and we will cancel every loan.

But if that nation I threatened stops doing wrong, I will cancel the destruction I intended to do to it.

But if that nation does what displeases me and does not obey me, then I will cancel the good I promised to do to it.

What I am saying is this: The law that came four hundred thirty years later does not cancel a covenant previously ratified by God, so as to invalidate the promise.
