Shemot 6:10-12

Orthodox Jewish Bible

¹⁰ And Hashem spoke unto Moshe, saying,

¹¹ Go in, speak unto Pharaoh Melech Mitzrayim, that he let the Bnei Yisroel go out of his land.

¹² And Moshe spoke before Hashem, saying, See, the Bnei Yisroel have not paid heed unto me; how then shall Pharaoh hear me, who am of aral sefatayim (uncircumcised lips, stumbling speech, sealed lips)?
