Firstborn

The sacrifice of firstling animals and redemption of firstborn sons were originally not related to the exodus story. When they were linked to the tenth plague, the narrative was adjusted to have YHWH also slaughter the Egyptian firstling animals.

The festival calendar in Deuteronomy 16 began as a short revision of the calendar in Exodus 23. As it was expanded to clarify and adjust its details, it merged its springtime Matzot festival with the Pesach offering, which was originally connected to the consecration of firstborn animals.

The Torah describes the Levites as a landless Israelite tribe who inherited their position by responding to Moses’ call to take vengeance against sinning Israelites. This account masks a more complicated historical process.

The exodus story, which is presented as the basis for many of the Torah’s rituals, is a secondary insertion in many of these contexts.

The Priestly Torah has two different conceptions of why/how the firstborn Israelites are exempt from serving as priests. Is a questionable firstborn census an effort to weigh in on this dispute?
