Exodus 7:18
“Also, the fishes that are in the river will die, and the waters will be polluted, and the Egyptians will be afflicted when they drink the water of the river.' "”
Verse Explanation
A saved explanation for Exodus 7:18.
Plain-language explanation
God warns that the waters of the Nile will be struck: the fish will die and the river will become polluted. As a result, the Egyptians will suffer when they drink from it.
Catholic context
In the Exodus story, God’s plagues show that His power is above Pharaoh and above the “gods” people associated with nature. Many Catholics see these events as a serious call to repentance—God does not merely disrupt creation, but uses it to confront sin and injustice.
Historical background
At the time, the Nile was essential for life in Egypt—food (including fish), irrigation, and daily drinking water depended on it. A contamination of the river would have been a direct, visible blow to Egyptian society and confidence, making the spiritual and political message impossible to ignore.
Reflection
This verse reminds us that sin doesn’t stay “contained.” What begins as pride and hard-heartedness can spread outward as harm to others. God’s warning also invites us to notice when our choices make life worse for the people around us.
Practical takeaway
When you notice something in your life (or community) that is harming others, don’t wait—invite change early. Choose repentance and repair: reduce what pollutes your relationships, your environment, or your conscience (truth, charity, and accountability).
Prayer
Lord, when You confront us with the truth, give us courage to turn away from what harms others. Cleanse the waters of our hearts, strengthen our faith, and help us choose repentance and mercy. Through Christ our Lord. Amen.
