Hebrews 8:10-11

10But this is the new covenant I will make with the people of Israel on that day, says the Lord: I will put my laws in their minds, and I will write them on their hearts. I will be their God, and they will be my people.

11And they will not need to teach their neighbors, nor will they need to teach their relatives, saying, ‘You should know the Lord.’ For everyone, from the least to the greatest, will know me already.
