How did the literary parallelism known as “progression” find its way into the Book of Mormon?

The type of parallelism known as progression involves parallel phrases that build up to a climactic conclusion. There are many examples of progression in the Book of Mormon such as:

2 Nephi 15:29

They shall roar like young lions;
yea, they shall roar,
and lay hold of the prey, and shall carry away safe, and none shall deliver.

2 Nephi 28:23

Yea, they are grasped with death, and hell;
and death, and hell,
and the devil, and all that have been seized therewith must stand before the throne of God, and be judged according to their works, from whence they must go into the place prepared for them, even a lake of fire and brimstone, which is endless torment.

Mosiah 21:26

Nevertheless, they did find a land which had been peopled;
yea, a land which was covered with dry bones;
yea, a land which had been peopled and which had been destroyed;
and they, having supposed it to be the land of Zarahemla, returned to the land of Nephi, having arrived in the borders of the land not many days before the coming of Ammon.

Why does this not sound like something young Joseph Smith would have dictated?
