3 x 3 Plagues on Egypt

James Jordan claims the first nine plagues against Egypt come in three cycles of three each.

First cycle: 1. Blood, 2. Frogs, 3. Gnats
Second cycle: 4. Flies, 5. Livestock, 6. Boils
Third cycle: 7. Hail, 8. Locusts, 9. Darkness

Each cycle begins with YHWH telling Moses to "Rise up early in the morning and present yourself to Pharaoh" or "Go to Pharaoh in the morning" Ex 7:15, 8:20, and 9:13. (Oh, and in the first two cycles, Moses comes to Pharaoh while he is down at the water.)

The second plague in each cycle begins by YHWH commanding Moses, "Go in to Pharaoh." Ex 8:1, 9:1, and 10:1.

The third plague in each cycle comes without any warning. God simply commands Moses or Aaron to "stretch out their hand to heaven." Ex 8:16-17, 9:8, and 10:21.
