Exodus 7:26

²⁴And all the Egyptians dug round about the river, so as to drink water, for they could not drink water from the river.

²⁵And seven days were fulfilled after the Lord had smitten the river.

— Exodus 7:26 —

²⁷And if thou wilt not send them forth, behold, I afflict all thy borders with frogs:

²⁸and the river shall teem with frogs, and they shall go up and enter into thy houses, and into thy bedchambers, and upon thy beds, and upon the houses of thy servants, and of thy people, and on thy dough, and on thine ovens.
