🔼The name Merari in the Bible
Merari is a son of Levi and brother of Kohath and Gershon (Genesis 46:11). His family is called the מררי, the Merarites, which is spelled the same as the name Merari (Numbers 26:57). The duties of the Merarites were to take care of the framework of the tabernacle: pillars and sockets of the tent as well as the surrounding court (Numbers 3:36-37).
🔼Etymology of the name Merari
The name Merari, like other Levites names, is probably of Egyptian origin and may have originally meant Beloved. In Hebrew, however, it looks like it has to do with the verb מרר (marar) meaning be bitter, strengthen, strong:

The letter yod on which our name Merari ends may be due to a possessive form, and the name Merari may mean My Bitterness or My Strength. For a meaning of the name Merari, NOBSE Study Bible Name List reads Bitter. Jones' Dictionary of Old Testament Proper Names reads Bitterness.
