In the Old Testament, when Moses splits the Red Sea, who is first to walk through the split bodies of water?

Answer 1

Since Israel crossed the sea in one night, it could hardly be assumed that the waters parted in a narrow channel. Rather, the channel may have been a kilometer or more in width. Though in fairly close marching formation, such a group, along with what wagons they had, their baggage, and their cattle, even when rather closely ranked, would occupy an area of perhaps 8 sq km (3 sq mi) or more. It appears, therefore, that the sea-opening allowed the Israelites to cross on a fairly wide front. If there was about a 1.5-km (1 mi) front, then the depth of the Israelite column would probably be about 5 km (3 mi) or more. If it was about a 2.5-km (1.5 mi) front, the depth might be about 3 km (2 mi) or more. It would take such a column several hours to get into the seabed and travel across it. While they did not go in panic, but maintained their battle formation, they would no doubt move with considerable haste.
As to Who crossed first...its anyone's Guess.

Aaron

Answer 3

According to Exodus 14:21-22, no one person was specifically named. So we don't know. Whoever he or she was, had to have a lot of faith!
