Moses and Aaron did just as the Lord had commanded. He raised his staff in the presence of Pharaoh and his officials and struck the water of the Nile, and all the water was changed into blood. The fish in the Nile died, and the river smelled so bad that the Egyptians could not drink its water. Blood was everywhere in Egypt. Exodus 7:20
When Pharaoh dared to vex the saints,
And thus provoked their God,
Moses was sent at their complaints,
Armed with his dreadful rod.
He called for darkness; darkness came
Like an o’erwhelming flood;
He turned each lake and every stream
To lakes and streams of blood.
He gave the sign, and noisome flies
Through the whole country spread;
And frogs in croaking armies rise
About the monarch’s bed.
Through fields, and towns, and palaces,
The tenfold vengeance flew;
Locusts in swarms devoured their trees,
And hail their cattle slew.
Then by an angel’s midnight stroke
The flower of Egypt died;
The strength of every house was broke,
Their glory and their pride.
Now let the world forbear its rage,
Nor put the church in fear;
Israel must live through every age,
And be th’Almighty’s care.
