"no longer shall they say to each other 'know the Lord'"

I think I'll use this favorite passage from Jeremiah 31 for our prayer group tonight:

The days are surely coming, says the Lord,
when I will make a new covenant
with the house of Israel and the house of Judah.
It will not be like the covenant that I made with their ancestors
when I took them by the hand
to bring them out of the land of Egypt—
a covenant that they broke,
though I was their husband, 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 within them,
and I will write it on their hearts;
and I will be their God,
and they shall be my people.

No longer shall they teach one another,
or say to each other, "Know the Lord,"
for they shall all know me,
from the least of them to the greatest, says the Lord;
for I will forgive their iniquity,
and remember their sin no more.
