The 237th mitzvah is that we are commanded to follow the laws regarding [damage caused by] an ox.

The source of this commandment is G‑d's statement1 (exalted be He), "If an ox gores [a man or woman...]", and the verse,2 "If one person's ox injures the ox of another person...."

The details of this mitzvah are explained in the first six chapters of tractate Bava Kama.
