Jeremiah 8:8

its all about Talmud.
Talmud has two components:

1) Mishnah (Hebrew: משנה , c. A.D. 200), a written compendium of Rabbinic Judaism's Oral Torah

2) the Gemara (c. A.D. 500), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the
Hebrew Bible.

the corruption in jeremiah 8:8 is not about the scripture itself,but jewish commentaries,misused of the law written by rabbi and scribes.

JESUS KICKS AGAINST SCRICTURUAL CORRUPTION USE BY PHARISEES AND SCRIBE

MATTHEW 23:23
"How terrible it will be for you, scribes and Pharisees, you hypocrites! You give a tenth of your mint, dill, and cummin, but have neglected the more important matters of the Law: justice, mercy, and faithfulness. These are the things you should have practiced, without neglecting the others.

MARK 7:3
Now in holding to the tradition of the elders, the Pharisees and all the Jews do not eat until they wash their hands ceremonially.

MARK 7:8
"You neglect God's Commandment: you hold fast to men's traditions."

MATTHEW 15-6
Why do thy disciples transgress the tradition of the elders ? for they wash not their hands when they eat bread.3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition? 4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. 5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; 6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition.

ITS A SERIOUS MATTER
