Proof of abrogation from the Bible

There are many commandments in the Bible that changed. Instead of discussing them I give concrete references for abrogation declared in the Bible.

‘For the priesthood being changed, there is made of necessity a change also of the law.’ (Hebrews 7:12)

Well known Christian commentator Adam Clarke writes under this verse:

‘The priesthood, therefore, being changed, Jesus coming in the place of Aaron, the law of ordinances and ceremonies, which served only to point out the Messiah, must of necessity be changed also.’

Lost books of the Bible

In fact there were many books to which even the authors of the Canonical books also referred but they are lost or at least not in the Bible.

Some of them are:

1- The Book of the Wars of the Lord mentioned in Numbers 21:14

2- Book of Jasher mentioned in Joshua 10: 13 etc

3- Book of Nathan the Prophet mentioned in 2-Chronicles 9: 29

4- Acts of Rehoboam & Book of Shemaiah the prophet mentioned in 2-Chronicles 12:15
5- Book of the acts of Solomon mentioned in 1-Kings 11:41

6- Acts of Uzziah mentioned in 2-Chronicles 26:22

This proves that the teachings of the prophets have been lost. Do Christians have any scriptural proof or historical evidence that nothing of value has been lost in these books and their teachings and records have been preserved in their so-called canon now?

All this exposes the liars who try to put the authenticity Book of Islam to doubt while their own book of authority is in the worst condition on the very accounts they try to challenge Quran.
