And the 53rd mitzvah is that we are commanded regarding the re'iyah offering.1

The source of this commandment is G‑d's statement2 (exalted be He), "Three times each year, all your males shall be seen in the presence of G‑d your L‑rd."

This commandment is that each man, together with each male child capable of walking on his own, must travel to the Temple and sacrifice a burnt offering upon arrival. This burnt offering which is brought when he arrives is called an olas re'iyah.

We have already mentioned previously3 the statement of our Sages,4 "The Jewish people were given three commandments to fulfill on the festivals: Chagigah, re'iyah and simchah."

The details of this mitzvah — i.e. of the re'iyah offering, have also been explained in tractate Chagigah.5 Women are not obligated in this commandment as well.
