And seven days were fulfilled, after that the Lord had smitten the
river. And the Lord spake unto Moses, "Go in unto Pharaoh, and say unto
him, 'Thus saith the Lord, Let my people go, that they may serve me. And
if thou refuse to let them go, behold, I will smite all thy borders with
frogs: and the river shall swarm with frogs, which shall go up and come
into thine house, and into thy bedchamber, and upon thy bed, and into
the house of thy servants, and upon thy people, and into thine ovens,
and into thy kneading-troughs: and the frogs shall come up both upon
thee, and upon thy people, and upon all thy servants.'"
And the frogs came up, and covered the land of Egypt. Then Pharaoh
called for Moses and Aaron, and said, "Entreat the Lord, that he take
away the frogs from me, and from my people; and I will let the people
go, that they may sacrifice unto the Lord."
And the frogs died, but when Pharaoh saw that there was respite, he
hardened his heart.
