Psalm 78:13 recounts the same event — God divided the sea and led them through, making water stand like a heap.

Psalm 106:9 describes God rebuking the Red Sea and leading them through the depths — identical miracle.

Psalm 66:6 also recalls God turning the sea into dry land — a parallel poetic retelling of the same miracle.

Exodus 14:22 records the actual crossing on dry ground — the event this psalm summarizes.
