29 And Moses said, Behold, I go out from thee, and I will entreat the LORD that the swarms [of flies] may depart from Pharaoh, from his servants, and from his people, to-morrow: but let not Pharaoh deal deceitfully any more, in not letting the people go to sacrifice to the LORD.
29
Moses answered, “As soon as I leave you, I will pray to the LORD, and tomorrow the flies will leave Pharaoh and his officials and his people. Only let Pharaoh be sure that he does not act deceitfully again by not letting the people go to offer sacrifices to the LORD.”
