רֵ֘אשִׁ֤ית חָכְמָ֨ה ׀ יִרְאַ֬ת יְהוָ֗ה שֵׂ֣כֶל ט֭וֹב לְכָל־עֹשֵׂיהֶ֑ם תְּ֝הִלָּת֗וֹ עֹמֶ֥דֶת לָעַֽד׃
여호와를 경외함이 곧 지혜의 근본이라 그 계명을 지키는 자는 다 좋은 지각이 있나니 여호와를 찬송함이 영원히 있으리로다
Zohar
Rabbi Aba said, "Serve Hashem in fear" 1. What fear is meant here? As we have established, it is written, "The fear of Hashem is the beginning of knowledge" (Mishlei 1:7) and "the fear of Hashem is the beginning of wisdom" (Tehilim 111:10), so the Holy One, blessed be He, is referred to in this name, "Fear of Hashem," Rabbi Elazar said: "Serve Hashem in fear," he who wishes to perform the service of his Master, from what point should he begin and to which area should he aim his service in order to unify the name of his Master? He repeats his words "with fear," because fear (which corresponds to Malchut) is the start (of service) going from below upwards.
Zohar
בְּרֵאשִׁית. Rabbi Chiya opened the discussion with the verse, "The fear of Hashem is the beginning of wisdom; good understanding have all they who do His commandments; His praise endures forever" (Ps. 111:10). Of the phrase, "the beginning of wisdom," this verse have read 'the fear of Hashem is the end of wisdom,' because the fear of Hashem (is the secret of Malchut), which is at the end of Chochmah! She (Malchut) is the beginning or the first stage that opens the entrance to the level of the supernal Chochmah (Wisdom). So it is written, "Open to me the gates of righteousness" (Ibid. 118:19), "this is the gate to Hashem" (Ibid. 20). Assuredly, if he does not enter this gate, he shall never reach the Supernal King, because He is exalted, hidden, and concealed, and has made gates for Himself, one behind the other.
