הלכה על חגיגה 12:7

That is that He commanded us to ascend to the Temple three times a year. And that is His, may He be exalted, saying, "Three times a year shall you have a holiday for me" (Exodus 23:14). And it is already explained in Scripture that this holiday is that all who ascend do so with a sacrifice to offer. And behold that this command has been repeated twice. And their language (Chagigah 6b) is, "Three commandments are practiced on the festival - the festival-offering, the sight-offering and the joy-offering." And the content of this festival-offering is that it be offered as a peace offering. But women are not obligated to do it. And the regulations of this commandment have already been explained in Tractate Chagigah. (See Parashat Mishpatim; Mishneh Torah, Festival Offering.)
