In Moses 1:8 we see an example of repeated conjunctions:
And it came to pass that Moses looked, and beheld the world upon which he was created; and Moses beheld the world and the ends thereof, and all the children of men which are, and which were created; of the same he greatly marveled and wondered. (emphasis added)
Repeated conjunctions are a classic Hebrew rhetorical device which we would not expect to see in English. In fact, many examples of polysyndeton were removed in the King James Version of the Bible.
Why would Joseph Smith repeat conjunctions like this? How would he know about this technique?
