Use this verse as a geography lesson for the Mormon. There has never been a river that empties into theRed Sea. It is surrounded by wilderness (desert) only. Ironically a canal was built to bring in water about 400 years ago and that is the only water that is anywhere in this area.
1 Nephi 2:8; “And it came to pass that he called the name of the river, Laman, and it emptied into the Red Sea; and the valley was in the borders near the mouth thereof.”
