מעשה העולה, שנאמר: "אִם עוֹלָה קָרְבָּנוֹ" (ויקרא א, ג).
Why · Sefer HaChinuch #115
Procedure of the burnt-offering
“From the roots of the commandment are what you will see at the end of my words. However, I am afraid of drawing close to the Dwelling of G-d, as I know that “anyone who comes close, who comes close” that has not sufficiently sanctified himself “will not see the House and live.””
