Exodus 14:19 And the angel of God, which went before the camp of Israel, removed and went behind them; and the pillar of the cloud went from before their face, and stood behind them. 20 And it came between the camp of the Egyptians and the camp of Israel; and it was a cloud and darkness to them, but it gave light by night to these: so that the one came not near the other all the night.
[Patriarchs & Prophets pp 287] As the darkness of night deepened, the wall of cloud became a great light to the Hebrews, flooding the entire encampment with the radiance of day. Then hope returned to the hearts of Israel. And Moses lifted up his voice unto the Lord. “And the Lord said unto Moses, Wherefore criest thou unto Me? speak unto the children of Israel, that they go forward. But lift thou up thy rod, and stretch out thine hand over the sea, and divide it: and the children of Israel shall go on dry ground through the midst of the sea.”
The psalmist, describing the passage of the sea by Israel, sang, “Thy way was in the sea, and Thy paths in the great waters, and Thy footsteps were not known. Thou leddest Thy people like a flock, by the hand of Moses and Aaron.” Psalm 77:19, 20, R.V. As Moses stretched out his rod the waters parted, and Israel went into the midst of the sea, upon dry ground, while the waters stood like a wall upon each side. The light from God's pillar of fire shone upon the foam-capped billows, and lighted the road that was cut like a mighty furrow through the waters of the sea, and was lost in the obscurity of the farther shore.
“The Egyptians pursued, and went in after them to the midst of the sea, even all Pharaoh's horses, his chariots, and his horsemen. And it came to pass, that in the morning watch the Lord looked unto the host of the Egyptians through the pillar of fire and of the cloud, and troubled the host of the Egyptians.” The mysterious cloud changed to a pillar of fire before their astonished eyes. The thunders pealed and the lightnings flashed.
Psalms 77:17 The clouds poured out water: the skies sent out a sound: thine arrows also went abroad. 18 The voice of thy thunder was in the heaven: the lightnings lightened the world: the earth trembled and shook. 19 Thy way is in the sea, and thy path in the great waters, and thy footsteps are not known.
May God add His blessing to the study of His word. “Good night” and God bless!
