“They did not keep in mind his power.

They did not remember

The day when he redeemed them from their foe.

He displayed his signs in Egypt.

He displayed his miracles in the fields of Zoan.

He turned their rivers to blood.

They could not drink of their streams.

He sent swarms of flies among them.

The flies devoured them.

He sent frogs among them,

The frogs destroyed them.

He gave their crops to the caterpillar.

He gave the fruit of their labor to the locust.

He destroyed their vines with hail.

He destroyed their sycamores with frost.

He gave over their cattle to the hail.

He gave their flocks to thunderbolts.

He let loose on them his fierce anger.

He let loose on them his wrath.

He let loose on them his indignation.

He let loose on them his distress.

He let loose a company of destroying angels.

He made a path for his anger.

He did not spare them from death.

He gave their lives over to the plague.

He struck all the first-born in Egypt.

He stuck the first issue of their strength

In the tents of Ham.”

Here the psalmist recalls the powerful acts recorded in Exodus, chapters 7-12, about the great plagues in Egypt. He wanted to recall the great events that God did in Egypt for them against their foes. He lists the various signs or miracles that took place in the Egyptian fields of Zoan or Ramses in order to save them and bring them out of Egypt. First he turned all their streams to blood. Then he let loose swarms of flies, frogs, caterpillars, and locusts that destroyed their crops. Then he let loose with hail and thunder that destroyed their cattle and herds. He then let loose the destroying angels that brought death. They struck down all the first born people and animals that were living in Ham, another word for Egypt based on Genesis. Clearly the plagues of Egypt were part of Israelite folklore built into the Israelite psyche.
