In Exodus 8:17, Aaron obeys the command from verse 16 and strikes the dust, bringing the gnats — immediate fulfillment.

In Exodus 8:5, Aaron is instructed to stretch his staff over waters for frogs — the same pattern of command to Aaron for a plague.

In Exodus 7:19, Aaron is told to stretch his staff over waters for the first plague — same method used for the third plague here.

In Exodus 9:8, Moses and Aaron take ash for the plague of boils — another plague command with a different action but similar structure.

In Exodus 9:22, Moses stretches his hand toward heaven for hail — another plague initiation pattern, though Moses acts alone here.

Psalm 105:31 poetically recalls this same plague: 'He spoke, and there came gnats' — a later poetic retelling of the event.
