“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 that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the Lord. But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people. No more shall every man teach his neighbor, and every man his brother, saying, ‘Know the Lord,’ for they all shall know Me, from the least of them to the greatest of them, says the Lord. For I will forgive their iniquity, and their sin I will remember no more.” (Jeremiah 31: 31-34)
In Jeremiah 31:31, the phrase "days are coming", usually introduces a special occasion of divine intervention in history. As contrasted with the Mosaic and Deuteronomic covenant, Jeremiah speaks of a new covenant with the house of Israel and house of Judah. According to Jeremiah 11:10, both kingdoms had broken God’s covenant by rejecting His words and by worshiping other gods.
