Psalm 105:29
“He turned their waters into blood, and slew their fish.”
KJV
Read in Psalm 105Meaning
The water plague is one part of escalating judgment in the Exodus memory.
Israel in Egypt, Moses, and the signs of judgment
The psalm recounts Israel's growth, Egyptian hostility, the sending of Moses and Aaron, and the plagues culminating in the death of the firstborn.
Read carefully
Psalm 105 recounts a particular Exodus event, not a universal disaster code.
Reflection
Recognize their severity rather than treating them as spectacle.
