The 210th mitzvah is that we are commanded to honor our parents.
The source of this commandment is G‑d's statement1 (exalted be He), "Honor your father and your mother."
The details of this mitzvah are explained in many Talmudic passages, mostly and primarily in tractate Kiddushin.2
The Sifra3 says, "What constitutes 'honor'? To give them food and drink, to clothe and cover them, to bring them inside and take them outside."
