Exodus 8:3-5

Young's Literal Translation

³ and the River hath teemed [with] frogs, and they have gone up and gone into thy house, and into the inner-chamber of thy bed, and on thy couch, and into the house of thy servants, and among thy people, and into thine ovens, and into thy kneading-troughs;

⁴ yea, on thee, and on thy people, and on all thy servants do the frogs go up.'

⁵ And Jehovah saith unto Moses, `Say unto Aaron, Stretch out thy hand, with thy rod, against the streams, against the rivers, and against the ponds, and cause the frogs to come up against the land of Egypt.'
