Jeremiah 31:31-34
“ Indeed, a time is coming,” says the LORD,“ when I will make a new covenant with the people of Israel and Judah.It will not be like the old covenant that I made with their ancestors when I delivered them from Egypt. For they violated that covenant, even though I was like a faithful husband to them,” says the LORD.“ But I will make a new covenant with the whole nation of Israel after I plant them back in the land,” says the LORD.“ I will put my law within them and write it on their hearts and minds. I will be their God and they will be my people.“ People will no longer need to teach their neighbors and relatives to know me. For all of them, from the least important to the most important, will know me,” says the LORD.“ For I will forgive their sin and will no longer call to mind the wrong they have done.”
Hebrews 8:7-12
For if that first covenant had been faultless, no one would have looked for a second one.But showing its fault, God says to them,“ Look, the days are coming, says the Lord, when I will complete a new covenant with the house of Israel and with the house of Judah.“ It will not be like the covenant that I made with their fathers, on the day when I took them by the hand to lead them out of Egypt, because they did not continue in my covenant and I had no regard for them, says the Lord.“ For this is the covenant that I will establish with the house of Israel after those days, says the Lord. I will put my laws in their minds and I will inscribe them on their hearts. And I will be their God and they will be my people.“ And there will be no need at all for each one to teach his countryman or each one to teach his brother saying,‘ Know the Lord,’ since they will all know me, from the least to the greatest.“ For I will be merciful toward their evil deeds, and their sins I will remember no longer.”
