What Does Exodus 13:4 Mean?

Today, in the month of Abib, you are going out. The calendar specification of the departure, the month of Abib, names the spring month of the Exodus for the first time (its later Babylonian name, Nisan, replaces Abib in post-exilic texts). Abib means "ripened ears" or "springtime grain": the month when the Barley crop begins to ripen, approximately March-April. The agricultural name of the month grounds the Exodus in the natural-cycle reality of Israel's Near Eastern world: the liberation happened in the spring, in the growing-season's beginning, when the land was renewing after winter.

The agricultural timing of the Exodus is theologically significant: spring is the season of new life, new growth, and new beginnings in the ancient world's calendar. Israel's liberation happens in the season of renewal; the new nation is born in the spring of the year. The spring timing connects the Exodus to the creation-renewal pattern: just as the earth renews in Abib, Israel is renewed and reconstituted as a people in the same month. The Passover's spring timing is built into its annual observance. Pesach is a spring feast because the Exodus happened in spring.

The naming of Abib is also the calendar-anchor for the agricultural feast system that the Torah will develop: the Feast of Unleavened Bread in Abib is the first of the three pilgrimage feasts (Passover-Matzot in Abib/Nisan, Shavuot/Pentecost seven weeks later, and Sukkot/Tabernacles in the fall). The spring-fall-spring rhythm of Israel's feast calendar is governed by the Abib Passover as its anchoring first event. The agricultural and theological calendars are coordinated from the Exodus outward.
