Hebrews 8:10-11

8:10For 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.

8:11And 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.
