Kabbalah Keluaran 5:1: Sha'arei Orah

וְאַחַ֗ר בָּ֚אוּ מֹשֶׁ֣ה וְאַהֲרֹ֔ן וַיֹּאמְר֖וּ אֶל־פַּרְעֹ֑ה כֹּֽה־אָמַ֤ר יְהוָה֙ אֱלֹהֵ֣י יִשְׂרָאֵ֔ל שַׁלַּח֙ אֶת־עַמִּ֔י וְיָחֹ֥גּוּ לִ֖י בַּמִּדְבָּֽר׃

Sesudah itu Musa dan Harun datang dan berkata kepada Firaun, “Beginilah firman Yang Mahakekal, Allah Israel: Biarkanlah umat-Ku pergi, supaya mereka merayakan hari raya bagi-Ku di padang gurun.”

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.’”
