29. And Mosheh said, “See, when I leave you I shall pray to יהוה, and tomorrow the swarms of flies shall depart from Pharaoh, from his servants, and from his people. But do not let Pharaoh again deceive, not to let the people go to slaughter to יהוה.”
30. And Mosheh went out from Pharaoh and prayed to יהוה.
31. And יהוה did according to the word of Mosheh and removed the swarms of flies from Pharaoh, from his servants, and from his people. Not one remained.
32. But Pharaoh hardened his heart at this time too, and did not let the people go.
