Exodus 14:21 - Wesley's Explanatory Notes

We have here the history of that work of wonder which is so often mentioned both in the Old and New Testament. An instance of God's almighty power in dividing the sea, and opening a passage through the waters. It was a bay, or gulf, or arm of the sea, two or three leagues over. The God of nature has not tied himself to its laws, but when he pleases dispenseth with them, and then the fire doth not burn, nor the water flow. They went through the sea to the opposite shore; they walked upon dry land in the midst of the sea; and the pillar of cloud being their rereward, the waters were a wall to them on their right hand, and on their left. Moses and Aaron it is likely ventured first, into this untrodden path, and then all Israel after them; and this march through the paths of the great waters would make their march afterwards through the wilderness less formidable. This march through the sea was in the night, and not a moon — shine night, for it was seven days after the full moon, so that they had no light but what they had from the pillar of fire. This made it the more awful, but where God leads us, he will light us; while we follow his conduct we shall not want his comforts.
