If there were any mistakes, it would be in the translations. But even in the different translations, the same points are carried out in all the scriptures. Even if the exact word is not used to translate the original hebrew and greek writings, the same spiritual lesson comes across. There are NO mistakes by the authors themselves in the original writings. Even though man wrote the bible, I believe they were inpired and written with the finger of God. That's why biblical writings don't contradict. The bible has ONE author and ONE gospel. Moses' writings are Jesus' words. It's called the word of God for a reason.
