Negative Commandment 80 (Digest)
Ascending the Altar via Steps
"You shall not go up by steps to My altar"—Exodus 20:23.
We are forbidden from ascending the Temple Altar with stairs, in order to avoid taking broad steps when going up. Rather, one should walk up the altar on a ramp, going "heel to toe" (i.e., using small, humble steps).
