Revised Common Lectionary, Year A, Proper 18 (series reading)

The Revised Common Lectionary appoints Exodus 12:1-14 as its OT series reading for this coming Sunday. It is part of a nine week series from the book of Exodus that began two weeks ago with the description of the Israelite’s slavery in Egypt and the birth of Moses. It continues through the deliverance at the Sea of Reeds, the journey to Sinai, the giving of the law, and the golden calf incident.

This passage, which comes from HS, is set as an interruption to the story of the final plague - the killing of the firstborn. It provides the law for the Feast of Unleavened Bread, placing the instructions for the feast in the middle of the story of Passover. It is immediately followed by the command to leave Egypt.

These instructions show the standard Priestly concern with the calendar. It sets up the month of Passover as the first month of the year. This places the beginning of the year in the Spring around the vernal equinox. This would later be changed in the Jewish calendar, which moved the beginning of the year to Rosh Hashannah in the Fall, near the autumnal equinox. 1 The theology of connecting the new year with the Passover is clear: just as the final plague and deliverance from Egypt begin Israel’s new life with God, so does the remembrance of that event mark the beginning of the new year.

The Israelites are commanded to slaughter a lamb and place the blood on the lintel of the door. The requirement of the lamb and the command that it be entirely eaten before the morning suggests that the lamb is intended as a peace / fellowship offering offered for giving thanks (Leviticus 7:11-15).2 In no way is it viewed as a sin offering. Although this passage does not describe the lamb as a sacrifice, the Priestly layers in the Pentateuch viewed all killing of animals as a sacrifice (a view which the Deuteronomists did not share). Of course, the picturing of the Passover according to the Priestly sacrificial scheme is a later interpretation of an earlier feast.


  1. It should be noted that some scholars argue that originally the New Year was in the Fall and see the Priestly author’s concept of it falling in the Spring as an innovation. [back]
