A common accusation by Islam, against the Torah and BIble is to twist Jeremiah 8:8, out of context, and claim it asserts the *Bible is CHANGED*.
However, actually READING THE CONTEXT shows that in the VERY NEXT VERSE, Jeremiah assert that the Wise "REJECT the Word of the Lord" - something *IMPOSSIBLE* to condemn them for if the Word of God NO LONGER EXISTS.
