And Moses said to Pharao: Set me a time when I shall pray for thee, and for thy servants, and for thy people, that the frogs may be driven away from thee and from thy house, and from thy servants, and from thy people; and may remain only in the river.
And the river shall bring forth an abundance of frogs: which shall come up, and enter into thy house, and thy bedchamber, and upon thy bed, and in the houses of thy servants, and to thy people, and into thy ovens, and into the remains of thy meats.
And the Lord said to him as he was returning into Egypt: See that thou do all the wonders before Pharao, which I have put in thy hand. I shall harden his heart, and he will not let the people go.
