There is a #chiasm in the #10plagues of Egypt:

a. Blood
.b. Frogs
..c. Lice
...d. Flies
....e. Cattle
....e. Man/beast
...d. Hail
..c. Locust
.b. Darkness
a. Firstborn

Do you see the link between opposing plagues in the 10 Plagues chiasm?

Plagues 1/10: Both attacked the very life of Egypt: the Nile and firstborn sons.
Plagues 2/9: Ever taken a country road at night and seen frogs everywhere? Most frogs are nocturnal.
Plagues 3/8: The lice were the "finger of God" and the locusts came because Pharaoh sinned against God.
Plagues 4/7: Goshen was spared in both plagues.
Plagues 5/6: Both were directed against higher lifeforms, aka nephesh.
