I'm all ears, what cha got?
If you look at the etymology of "roll" as it was used when the King James was written, it defines it basically as a scroll with an official record... it's the word of God.
roll (n.)
early 13c., "rolled-up piece of parchment or paper" (especially one inscribed with an official record)
If that's not enough to convince us, God gives us a second witness through the dimensions of the roll. The dimensions are 20 and 10. 10 is easy to see, it represents the law or more specifically the entire Old Testament. An example of this would be "Am I not better to thee than 10 sons"... it's talking about Hannah's (foreshadowing the church) husband (foreshadowing Christ) is better to her than 10 commandments.
1Sa_1:8 Then said Elkanah her husband to her, Hannah, why weepest thou? and why eatest thou not? and why is thy heart grieved? am not I better to thee than ten sons?
The number 20 may be a little harder to see. 20 is the double portion of 10. It is the spirit in the law.
2Ki_2:9 And it came to pass, when they were gone over, that Elijah said unto Elisha, Ask what I shall do for thee, before I be taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me.
Num_32:11 Surely none of the men that came up out of Egypt, from twenty years old and upward, shall see the land which I sware unto Abraham, unto Isaac, and unto Jacob; because they have not wholly followed me:
This is getting long, so I will stop here for now. Plus if you don't buy this, you'll never buy the rest lol.
