29 and Moses saith, `Lo, I am going out from thee, and have made supplication unto Jehovah, and the beetle hath turned aside from Pharaoh, from his servants, and from his people -- to-morrow, only let not Pharaoh add to deceive -- in not sending the people away to sacrifice to Jehovah.'
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.”
