Talmud Bavli Shabbat on Fear as Prerequisite to the Study of the Six Orders of the Mishnah

"Reish Lakish said: What is implied by that which is written: 'The stability of your time and the strength of salvation is wisdom and knowledge; the fear of God is in His storehouse' (Isaiah 33:6)? 'Stability' - this refers to Seder Zera'im; 'your time' - this refers to Seder Mo'ed; 'the strength' - this refers to Seder Nashim; 'salvation' - this refers to Seder Nezikin; 'wisdom' - this refers to Seder Kodashim; 'and knowledge' - this refers to Seder Toharot. But even so, 'the fear of God is in His storehouse.'"
