Okay, show me a map of the area so I can see this river:
Hmmm, not seeing it. What do other sources say?
The Suez Canal only opened in 1869 and it's at least a five day walk to where it meets the Red Sea, according to modern conditions and as perceived by Google Maps. There are seasonal rivers in Eritrea...but that's in Africa, much more than three days away from Jerusalem. There's the Gulf of Aqaba, but it doesn't look like a river. And the Red Sea itself is quite salty, as Wikipedia announces:
Did you see the part about "lack of significant rivers or streams draining" into it?The salinity of the Red Sea is greater than the world average, approximately 4 percent. This is due to several factors:
- High rate of evaporation and very little precipitation.
- Lack of significant rivers or streams draining into the sea.
- Limited connection with the Indian Ocean, which has lower water salinity.
If there was a wadi, perhaps, that had seasonal water...but the family stayed camped there while Nephi and his brothers went back for the Brass Plates. If it was only a stream resulting from rainstorms, Lehi was not hoping for much when he wished his son Laman would be "continually running into the fountain of all righteousness."
Now let's see about rivers mentioned in the Bible, how many of them can be found today? Jordan, check. Tigris and Euphrates, check. The "river in Egypt," aka the Nile, check. Kishon, check.
Now perhaps there was some river that existed three days distance from Jerusalem and it emptied into the Red Sea, but has since silted over. But this is only one of the examples of how Book of Mormon geography and history look like they were invented for a novel.
