Sefer HaChinuch 490 ספר החינוך ת״צ

To not go up for the festival without a sacrifice: To not go up to the Choice House on the festival without a sacrifice that we will offer there — and that is the sacrifice that we explained above in this Order (Sefer HaChinukh 489), that is called the burnt-offering of being seen. And about this is it stated (Deuteronomy 16:16), “and they shall not appear empty before the face of the Lord.” The understanding of “face (pnei)” is like “in front of (lifnei).” And there I wrote from the roots of the commandment and all of its content. And this warning (negative commandment) is not practiced by females, [just] like the positive commandment that comes upon this is not practiced by females.
