Contradiction with Jeremiah 31:34
Jeremiah 31:34 speaks of God's promise to forgive iniquity and remember sins no more, which contrasts with Jeremiah 2:9, where God states that He will "plead" or contend with the people for their wrongdoing, emphasizing accountability rather than forgiveness.
Jeremiah 31:34: 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.
