Merari
According to the Torah, Merari was one of the sons of Levi, and the patriarchal founder of the Merarites, one of the four main divisions among the Levites in Biblical times. The Hebrew word Merari means sad, bitter or strong. The Merarites were charged with the transportation and care of the structural components of the tabernacle.
Richard Elliott Friedman attributes the genealogy to the Book of Generations, a document originating from a similar group and date to the priestly source. According to some biblical scholars, the Torah's genealogy for Levi's descendants is actually an aetiological myth reflecting the fact that there were four different groups among the levites - the Gershonites, Kohathites, Merarites, and ; according to the Jewish Encyclopedia, Levite was originally just a job title, deriving from the Minaean word lawi'u meaning priest, rather than having been the name of a tribe.
