And Israel saw that great work which the LORD did upon the Egyptians: and the people feared the LORD, and believed the LORD, and his servant Moses.
And Israel saw that great work which the LORD did upon the Egyptians: and the people feared the LORD, and believed the LORD, and his servant Moses.
Exodus 14:29 But the children of Israel walked upon dry land in the midst of the sea; and the waters were a wall unto them on their right hand, and on their left.
Exodus 14:30 Thus the LORD saved Israel that day out of the hand of the Egyptians; and Israel saw the Egyptians dead upon the sea shore.
Exodus 14:31 And Israel saw that great work which the LORD did upon the Egyptians: and the people feared the LORD, and believed the LORD, and his servant Moses.
The verse centers on "israel", "great", "lord", "upon", "egyptians", "people", and "feared". It is saying that the verse draws attention to "israel" and "great", so its meaning should be read from those terms before moving to application.
The prior verse says "Thus the LORD saved Israel that day...", giving immediate footing for "israel" and "great". In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "israel" and "great" with trust shaped by these words, not by a vague optimism outside the passage.
