Passage
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.
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.
Exodus 14:18 And the Egyptians shall know that I am the LORD, when I have gotten me honour upon Pharaoh, upon his chariots, and upon his horsemen.
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:
Exodus 14:20 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.
Exodus 14:21 And Moses stretched out his hand over the sea; and the LORD caused the sea to go back by a strong east wind all that night, and made the sea dry land, and the waters were divided.
Exodus 14:22 And the children of Israel went into the midst of the sea upon the dry ground: and the waters were a wall unto them on their right hand, and on their left.
The verse centers on "light", "darkness", "came", "between", "camp", "egyptians", "israel", and "cloud". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 19's "And the angel of God which went..." into verse 21's "And Moses stretched out his hand over...", so "light" and "darkness" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
