...Behold, days are coming,” declares the Lord, “when I will make a new covenant with the house of Israel and with the house of Judah, not like the covenant which I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them,” declares the Lord. “But this is the covenant which I will make with the house of Israel after those days,” declares the Lord, “I will put My law within them and on their heart I will write it; and I will be their God, and they shall be My people. (Jeremiah 31:31-33)
For if that first covenant had been faultless, there would have been no occasion sought for a second. For finding fault with them, He says, “Behold, days are coming, says the Lord, When I will effect a new covenant With the house of Israel and with the house of Judah; Not like the covenant which I made with their fathers On the day when I took them by the hand To lead them out of the land of Egypt; For they did not continue in My covenant, And I did not care for 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 into their minds, And I will write them on their hearts. And I will be their God, And they shall be My people. “And they shall not teach everyone his fellow citizen, And everyone his brother, saying, ‘Know the Lord,’ For all will know Me, From the least to the greatest of them. “For I will be merciful to their iniquities, And I will remember their sins no more.” When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear. (Hebrews 8:7-13)
