바로가 가로되 여호와가 누구관대 내가 그 말을 듣고 이스라엘을 보내겠느냐 나는 여호와를 알지 못하니 이스라엘도 보내지 아니하리라
Sha'arei Orah
Therefore, when Moshe went to Pharaoh as HaShem’s-יהו״ה emissary, blessed is He, he began with the word “Thus-Koh-כה,” since it is the opening by which to enter the Name HaShem-יהו״ה, blessed is He. This is as written,224Exodus 5:1 “Afterwards, Moshe and Aharon came and said to Pharaoh, ‘Thus-Koh-כה said HaShem-יהו״ה, the God of Israel, ‘Send out My people etc.’” The next verse continues,225Exodus 5:2 “Pharaoh replied: ‘Who is HaShem-יהו״ה that I should heed His voice to send Israel out? I do not know HaShem-יהו״ה.” Moshe therefore responded, “If you do not know HaShem-יהו״ה, then what you must know is that the first gateway through which one enters the knowledge of Him, is His Divine quality called, ‘Thus-Koh-כה.’”
