Exodus 7:20 Citation

In Exodus 7:20, Moses smites the Nile with this rod—directly referenced as 'the rod wherewith thou smotest the river' in Exodus 17:5.

Numbers 20:8-11 records a later water-from-rock episode with the same rod, but Moses strikes instead of speaking—a parallel miracle with a key difference.

Deuteronomy 8:15 recalls God bringing water from the rock of flint, directly referencing the miracle initiated in Exodus 17:5.
