Red Sea

Concise Bible Dictionary:

This sea is renowned in Old Testament history on account of the miraculous passage made for the Israelites, and the destruction of their enemies therein.
The Red Sea, situated on the east of Egypt and the west of South Arabia, is somewhat in the form of the letter Y. Its southern extremity opens into the Indian Ocean, from whence it runs N.N.W. for about 1,400 miles, when it divides into two branches; the one on the east being the Gulf of Akaba, about 112 miles long; and the one on the west, the Gulf of Suez, about 200 miles long. It is the latter that the Israelites crossed, and, as is supposed, farther north than the gulf now extends, but the position is not known. It is to this branch that the Suez Canal has been attached, opening a passage to the Mediterranean Sea.
THE PASSAGE OF THE RED SEA. The number of the Israelites was probably about two millions. They encamped by the sea shore and Pharaoh naturally thought they were entangled in the land. With his army and his chariots he pursued after them. The Israelites greatly feared, but Moses said, “Fear ye not, stand still, and see the salvation of Jehovah.” The angel of God and the pillar of the cloud went between the Israelites and the Egyptians. To the Israelites the cloud gave light, but to the Egyptians it was a cloud of darkness, all night. Moses stretched out his hand over the sea, and God caused a strong east wind to blow all that night, and the waters were divided, and the Israelites went over on dry land.
Pharaoh had not yet learned the power of Jehovah, and the Egyptians pursued them. God fought for the Israelites: He embarrassed the Egyptians, took off the chariot wheels, and thus so hindered them that they began to see that Jehovah was opposing them. It was, however, too late to retreat, Moses stretched forth his hand over the sea, and it returned in its strength, and they were overwhelmed. Their dead bodies were cast up on the sea shore.
The faith of the Israelites was confirmed by the destruction of the Egyptians: they feared Jehovah, and believed Jehovah and His servant Moses. He and the Israelites could then sing the song of redemption, and praise Him who had purchased them. He also would plant them in the mountain of His inheritance, yea, in the sanctuary which His hands had established. Jehovah shall reign forever and ever (Ex. 14-15).
