Exodus 14:21 fulfills the command in verse 16 — Moses stretches out his hand as instructed, and the sea parts.

In Exodus 4:2, the rod is first introduced as what Moses holds, establishing the instrument used here.

In Exodus 7:9, the same rod is used to perform a sign before Pharaoh, demonstrating its power.

Isaiah 43:16 recalls God making a way through the sea, a direct allusion to the Exodus miracle of dividing the waters.

In Numbers 20:8, Moses again uses the rod to bring water from a rock, a later water miracle.

Mark 4:39 shows Jesus commanding the sea to be still, demonstrating the same divine authority over waters that God displayed in dividing the Red Sea.
