Do Rambam’s 613 Talmud descriptions attempt to explain Hashem’s definitions for specified work or labor activities to avoid each Shabbos? How were Rambam and the Sages able to create their concepts of Hashem's laws instead of allowing Hashem’s gift to humankind who was given the gift of understanding of Torah’s commandments? The prophet Job stated G-d had given all humankind an understanding Job 32:7-9 אָ֭כֵן רֽוּחַ־הִ֣יא בֶאֱנ֑וֹשׁ וְנִשְׁמַ֖ת שַׁדַּ֣י תְּבִינֵֽם "But truly it is the spirit in men, The breath of Shaddai, that gives them understanding."
