Hebrews 8:6-12

But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.
For if that first covenant had been faultless, then no place would have been sought for a second.
Because finding fault with them, He says: “Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah—
not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the LORD.
For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people.
None of them shall teach his neighbor, and none his brother, saying, ‘Know the LORD,’ for all shall know Me, from the least of them to the greatest of them.
For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.”

1 Thessalonians 3:11-13

Now may our God and Father Himself, and our Lord Jesus Christ, direct our way to you.
And may the Lord make you increase and abound in love to one another and to all, just as we do to you,
so that He may establish your hearts blameless in holiness before our God and Father at the coming of our Lord Jesus Christ with all His saints.

Jeremiah 32:40-41

And I will make an everlasting covenant with them, that I will not turn away from doing them good; but I will put My fear in their hearts so that they will not depart from Me.
Yes, I will rejoice over them to do them good, and I will assuredly plant them in this land, with all My heart and with all My soul.
