And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
They shall teach no more ... every man his brother ... for they shall all know me from the least ... unto the greatest of them. True specially of Israel (Isaiah 54:13); secondarily true of believers (John 6:45; 1 Corinthians 2:10; 1 John 2:20).
I will forgive their iniquity, and ... remember their sin no more - (Jeremiah 33:8; Jeremiah 50:20; Micah 7:18-19) applying peculiarly to Israel (Romans 11:26-27); secondarily, all believers (Acts 10:43).
