The English word “feast” brings a table with it. Bread, wine, family, a long afternoon. The Hebrew word brings a calendar. Moed — plural moadim — is not a festival. It is an appointment: a fixed time, agreed in advance, at which two parties have arranged to meet. The dwelling in the wilderness was the ohel moed, the tent of the appointment, and the appointment was not with the tent. Everything in the word is about arriving somewhere at an hour you did not choose, because Someone else chose it and then told you when to come.
Leviticus 23 is the list, and the first thing to notice about it is a pronoun. These are not Israel’s feasts, offered up to Yahuah out of gratitude or invention. Twice in the opening verse, and again at the close of the chapter, He calls them His own. The moadim of Yahuah. My appointed times. The congregation does not host them. The congregation is summoned to them, the way a man is summoned to a hearing that was entered on the docket long before he was born.
