And they shall teach no more every man his neighbour, and every man his brother, saying, Know Jehovah; for they shall all know me, from the least of them unto the greatest of them, saith Jehovah: for I will pardon their iniquity, and their sin will I remember no more.
Jeremiah 31:32 not according to the covenant that I made with their fathers, in the day of my taking them by the hand, to lead them out of the land of Egypt; which my covenant they broke, although I was a husband unto them, saith Jehovah.
Jeremiah 31:33 For this is the covenant that I will make with the house of Israel, after those days, saith Jehovah: I will put my law in their inward parts, and will write it in their heart; and I will be their God, and they shall be my people.
Jeremiah 31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know Jehovah; for they shall all know me, from the least of them unto the greatest of them, saith Jehovah: for I will pardon their iniquity, and their sin will I remember no more.
Jeremiah 31:35 Thus saith Jehovah, who giveth the sun for light by day, the ordinances of the moon and of the stars for light by night, who stirreth up the sea so that the waves thereof roar, Jehovah of hosts is his name:
Jeremiah 31:36 If those ordinances depart from before me, saith Jehovah, the seed of Israel also shall cease from being a nation before me for ever.
The verse centers on "shall", "teach", "neighbour", "brother", "saying", "jehovah", and "least". It is saying that the verse draws attention to "shall" and "teach", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 33's "For this is the covenant that I..." into verse 35's "Thus saith Jehovah who giveth the sun...", so "shall" and "teach" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "shall" and "teach" with trust shaped by these words, not by a vague optimism outside the passage.
