Contradiction with Exodus 8:22
In Exodus 8:22, God differentiates between the Egyptians and His people, the Israelites, protecting the land of Goshen, showing His selective intervention, which contrasts with Exodus 7:20, where all of Egypt's water is affected indiscriminately.
Exodus 8:22: And I will sever in that day the land of Goshen, in which my people dwell, that no swarms [of flies] shall be there; to the end thou mayest know that I [am] the LORD in the midst of the earth.
Contradiction with Psalm 105:29
Psalm 105:29 states that God turned their waters into blood, aligning with Exodus 7:20; however, it more broadly attributes the plagues to God, whereas Moses and Aaron are the agents in Exodus 7:20.
Psalm 105:29: He turned their waters into blood, and slew their fish.
Contradiction with Ezekiel 14:19
In Ezekiel 14:19, the specificity and targeted action against a land for unfaithfulness emphasize divine precision, whereas the act in Exodus 7:20 is a blanket action affecting all Egyptian waters.
Ezekiel 14:19: Or [if] I send a pestilence into that land, and pour out my fury upon it in blood, to cut off from it man and beast:
Contradiction with Revelation 16:4
Revelation 16:4 speaks of the bowls of wrath turning rivers and springs to blood, an act in eschatological context affecting the wicked, differing from Exodus 7:20 where water turns to blood as an initial sign to reveal God's power.
Revelation 16:4: And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.
Contradiction with John 2:9
In John 2:9, Jesus turns water into wine at a wedding, showcasing a miracle of transformation with a positive and celebratory outcome, in stark contrast to the destructive change in Exodus 7:20.
John 2:9: When the ruler of the feast had tasted the water that was made wine, and knew not whence it was: (but the servants which drew the water knew;) the governor of the feast called the bridegroom,
Paradox #1
Exodus 7:20 describes an event where water turns into blood as a sign from God. Some people might see a contradiction in this event considering the scientific understanding of water and chemistry. Others might find inconsistencies when comparing it to other signs or miracles in the Bible, questioning why sometimes miracles are grand and other times more subtle. Additionally, the ethical implications of punishing a group of people through plagues might appear inconsistent with a message of love and mercy found in other parts of the Bible.
Paradox #2
One possible contradiction might be the transformation of water into blood. From a scientific perspective, turning a large body of water like the Nile into actual blood is not feasible, as it would require altering the chemical composition of water on a massive scale. Such a phenomenon lacks a natural explanation or mechanism in known science.
Paradox #3
The contradiction in this context could be the idea of using miraculous power in a harmful way, such as turning water into blood, which causes suffering to many people and creatures. It raises the question of why a benevolent power would cause harm to innocent beings to achieve a goal.
