Not to climb steps to the altar

The Torah commands that the altar be approached not by steps, but by a ramp (kevesh). Ascending by steps might cause one’s gait to expose nakedness, even if covered, which would be inappropriate before Hashem. The prohibition also instills a sense of reverence, ensuring that those who serve upon the altar do so with the utmost modesty and respect.

Rambam codifies that the altar was required to have a ramp, not stairs, and that even indirect exposure or immodesty was considered disrespectful. The Sages explain that if the Torah commands such sensitivity toward inanimate stones of the altar, how much more so must we be careful with the dignity of our fellow humans.

This mitzvah expresses the principle that holiness requires not only proper service but also refinement of conduct, humility, and modesty in approaching Hashem.
