21 Then Moses stretched out his hand over the sea, and the LORD drove the sea back by a strong east wind all night and made the sea dry land, and the waters were divided.22 And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left.23 The Egyptians pursued and went in after them into the midst of the sea, all Pharaoh's horses, his chariots, and his horsemen.
Exodus 14
5 When the king of Egypt was told that the people had fled, the mind of Pharaoh and his servants was changed toward the people, and they said, “What is this we have done, that we have let Israel go from serving us?”6 So he made ready his chariot and took his army with him,7 and took six hundred chosen chariots and all the other chariots of Egypt with officers over all of them.8 And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued the people of Israel while the people of Israel were going out defiantly.9 The Egyptians pursued them, all Pharaoh's horses and chariots and his horsemen and his army, and overtook them encamped at the sea, by Pi-hahiroth, in front of Baal-zephon.
