Hebrews 8:7-13 - A Superior Covenant
7 For if that first Agreement had been faultless, then there would have been no need for a second one. 8 For God found fault with the Israelites [or, possibly with the first Agreement], saying [Jer. 31:31ff], "Look, the Lord says, the time will come when I will make a New Agreement with the people of Israel and with the people of Judah. 9 [It will] not be like the Agreement that I made with their forefathers on the day I took them by the hand to lead them out of the country of Egypt. For they did not [continue to] keep my Agreement, so I did not regard them [as acceptable], says the Lord. 10 For this is the Agreement that I will make with the people of Israel in the coming days, says the Lord: I will put my laws into their minds, and I will also write them on their hearts. And I will be their God and they will be my people. 11 And everyone will not [have to] teach his neighbor or his brother [anymore], telling them to 'Know the Lord,' because all of them will know me [as their Lord], from the least [important] ones to the most important ones. 12 For I will be merciful to their wickedness [i.e., by forgiving them] and I will not remember their sins anymore."
13 [So], by saying "a New Agreement," God has made the first one obsolete. And that which is becoming obsolete and getting aged is ready to [completely] disappear.
