Thus there are many witnesses to the miracles attending the children of Israel as they were led out of Israel. The Book of Mormon is a major witness.
“Nephi Bore Testimony to Laman and Lemuel”
Nephi later speaks of “the God of our fathers, who were led out of Egypt, out of bondage, and also were preserved in the wilderness by him” and then identifies God as Jesus Christ (1 Nephi 19:10). Alma tells his son Helaman: “I will praise [God] forever, for he has brought our fathers out of Egypt” (Alma 36:28).
Moses Divides the Red Sea
21 And Moses stretched out his hand over the sea; and the LORD caused the sea to go back by a strong east wind all that night, and made the sea dry land, and the waters were divided.
22 And the children of Israel went into the midst of the sea upon the dry ground: and the waters were a wall unto them on their right hand, and on their left.
23 And the Egyptians pursued, and went in after them to the midst of the sea, even all Pharaoh’s horses, his chariots, and his horsemen.
27 And Moses stretched forth his hand over the sea, and the sea returned to his strength when the morning appeared; and the Egyptians fled against it; and the LORD overthrew the Egyptians in the midst of the sea.
28 And the waters returned, and covered the chariots, and the horsemen, and all the host of Pharaoh that came into the sea after them; there remained not so much as one of them.
29 But the children of Israel walked upon dry land in the midst of the sea; and the waters were a wall unto them on their right hand, and on their left. [Exodus 14:21–23; 27–29]
