Hebrews 8:6, 12-13

But now Jesus, our High Priest, has been given a ministry that is far superior to the old priesthood, for he is the one who mediates for us a far better covenant with God, based on better promises.

And I will forgive their wickedness, and I will never again remember their sins.” When God speaks of a “new” covenant, it means he has made the first one obsolete. It is now out of date and will soon disappear.
