'New Covenant' in the Bible

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:

For finding fault with them, he saith, Behold, the days come, saith the Lord, when 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. Now that which decayeth and groweth old is ready to vanish away.

And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
