“I will make
The land of Egypt
Desolate.
I will strip
The land
Of all
That fills it.
I will strike down
All
Who live in it.
Then they shall know
That I am Yahweh.”
Yahweh has this parting shot about the desolation of Egypt. He was going to strip the land of everything in it. He was going to strike down all those living there. Then they would come to recognize that Yahweh was God.
