Levi, the third son of Jacob and Leah, is a foundational figure in the history of the Israelites. His three sons—Gershon, Kohath, and Merari—became the heads of the Levitical clans, each with specific roles in the religious practices of Israel. The Gershonites were responsible for the care of the tabernacle's fabrics and coverings, the Kohathites for the sacred objects like the Ark of the Covenant, and the Merarites for the structural components of the tabernacle. This division of labor highlights the organized and communal nature of Israelite worship.
Levi's age of 137 years is mentioned to underscore the longevity and significance of his life, which is a common biblical motif for patriarchs. The Levites, as descendants of Levi, were set apart for religious duties, serving as priests and caretakers of the temple. This lineage is crucial for understanding the development of Israel's religious identity and the central role of the Levites in maintaining the covenant relationship with God. The passage underscores the importance of heritage and the transmission of faith and responsibilities through generations.
