R. Shimon bar Yohai is famously quoted in Berakhot 35b as believing that:
אפשר אדם חורש בשעת חרישה וזורע בשעת זריעה וקוצר בשעת קצירה ודש בשעת דישה וזורה בשעת הרוח תורה מה תהא עליה אלא בזמן שישראל עושין רצונו של מקום מלאכתן נעשית ע"י אחרים
Is it really possible that a man should plow during the plowing season, sow during the sowing season, harvest during the harvest season, thresh during the threshing season and winnow during the windy season? If that is the case, what will become of the Torah? Rather, it must be that when Israel performs the will of the Omnipresent, their work is carried out by others.
This view is often cited by those advocating for full-time torah study in place of earning a living. See e.g. here.
