Now Mount Sinai was completely covered with smoke because the Lord had descended on it in fire, and its smoke went up like the smoke of a great furnace, and the whole mountain shook violently.
“You should fear me!” says the Lord. “You should tremble in awe before me! I made the sand to be a boundary for the sea, a permanent barrier that it can never cross. Its waves may roll, but they can never prevail. They may roar, but they can never cross beyond that boundary.”
Because of this the earth will quake, and all who live in it will mourn. The whole earth will rise like the River Nile, it will surge upward and then grow calm, like the Nile in Egypt.
