'New Covenant' in the Bible

for, finding fault with them, He saith, "Behold, the days are coming, saith the Lord, when I will make a new covenant with the house of Israel, and the house of Judah;

In that He saith, "A new covenant," He hath made the first old: but the thing that is becoming old, and is wearing out with age, is near vanishing away.

And, for this cause, He is the Mediator of a new covenant, that, death having taken place for redemption from the transgressions against the first covenant, those who have been called may receive the promise of the eternal inheritance.

and to Jesus, the Mediator of a new covenant, and to the blood of sprinkling, speaking better things than Abel.
