'New Covenant' in the Bible

For finding fault with them, he saith, Behold, the days come, saith the Lord, That I will make a new covenant with the house of Israel and with the house of Judah;

In that he saith, A new covenant he hath made the first old. But that which is becoming old and waxeth aged is nigh unto vanishing away.

And for this cause he is the mediator of a new covenant, that a death having taken place for the redemption of the transgressions that were under the first covenant, they that 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 that speaketh better than that of Abel.
