27 These are they which spoke to Pharaoh Melech Mitzrayim, to bring out the Bnei Yisroel from Mitzrayim: these are that Moshe and Aharon.
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.
