“The sons of Merari were Mahli, Libni his son, Shimei his son, Uzzah his son, Shimea his son, Haggiah his son, and Asaiah his son.”
This genealogy of (1) Merari only goes 8 deep, much shorter compared to the other 2 sons of Levi. This lineage follows (2) Mahli and not Mushi. (3) Libni is the same name as son of Gershom. There are 16 biblical persons named (4) Shimei. There 3 people with the name of (5) Uzzah. The most famous Uzzah is the one who died while transporting the Ark of the Covenant in 2 Samuel, chapter 6. There also was a garden in Jerusalem, where King Manasseh was buried in 2 Kings, chapter 21. There were 4 people with the name of (6) Shimea in the biblical literature and it is very close to Shimei. This is the only mention of (7) Haggiah, while 4 people have the name (8) Asaiah. There is less emphasis on this clan of Levites. Their official functional roles were laid out in Numbers, chapter 4.
