Exodus 8:29-31

Darby Translation

²⁹ And Moses said, Behold, I go out from thee, and will intreat Jehovah; and the dog-flies will depart from Pharaoh, from his bondmen, and from his people, to-morrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to Jehovah.

³⁰ And Moses went out from Pharaoh, and intreated Jehovah.

³¹ And Jehovah did according to the word of Moses; and he removed the dog-flies from Pharaoh, from his bondmen, and from his people; there remained not one.
