”Today most academic scholars say that the Torah has multiple authors, and that its composition took place over centuries.”
What is right and what is wrong? Did Moses really write Genesis through Deuteronomy?
"Pentateuch" refers to the first five books of the Bible: Genesis, Exodus, Leviticus, Numbers and Deuteronomy.
"The evidence within the Pentateuch points to Mosaic authorship, since it clearly portrays Moses as the author of certain portions. “And Moses wrote all the words of the LORD” (Exodus 24:4, KJV). “And he took the book of the covenant, and read in the audience of the people” (Exodus 24:7, KJV). “And the Lord said to Moses, ‘Write these words; in accordance with these words I have made a covenant with you and with Israel’” (Exodus 34:27, RSV).
To these references many others could be added. Not only does the internal evidence of the Scriptures make it clear that Moses wrote the Pentateuch, but other Old Testament books make Mosaic authorship clear. Joshua 8:32 (KJV) refers to “the law of Moses, which he wrote.” Additional Old Testament references include I Kings 2:3, II Kings 14:6, and Joshua 23:6, which attribute to Moses the authorship of the Pentateuch."
