The 154th mitzvah is that we are commanded to rest on Shabbos.

The source of this commandment is G‑d's statement1, "And on the seventh day you shall rest."

This commandment is repeated many2 times in the Torah.

G‑d (exalted be He) has clearly stated that this cessation from melachah3 applies to us, our animals, and our servants.4

The details of this mitzvah are explained in tractate Shabbos and also in tractate Yom Tov.5
