Fig. 1- Hebrew Torah. This Scripture pre-dated the Koran by at least 2000 years. This is why the Bible is the standard to test all other revelations, especially the Koran.  We also note that the Torah, unlike the Koran of Mohammed, was written by literate men.  While scribes like Ezra compiled various writings, the original writings were the product of learned minds.

2 Peter 1:21, For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
