28. And it came to pass on the day when Hashem spoke unto Moshe in Eretz Mitzrayim,

29. That Hashem spoke unto Moshe, saying, I am Hashem: speak thou unto Pharaoh Melech Mitzrayim all that I say unto thee.

30. And Moshe said before Hashem, See, I am of aral sefatayim,and why should Pharaoh pay heed unto me.
