Psalms 78:44
“And had turned their rivers into blood; and their floods, that they could not drink.”
They remembered not his hand, nor the day when he delivered them from the enemy.
How he had wrought his signs in Egypt, and his wonders in the field of Zoan:
And had turned their rivers into blood; and their floods, that they could not drink.
He sent divers sorts of flies among them, which devoured them; and frogs, which destroyed them.
He gave also their increase unto the caterpiller, and their labour unto the locust.
