There is a fine paronomasia in the original. Levi is desired from {lawah,} to join, couple, associate; hence Moses says, the Levites {yillawoo,} "shall be joined," or associated, with the priests: they shall conjointly perform the sacred office, but the priests shall be principal, the Levites their associates or assistants.
minister ............ before <08334 06440> [minister.]
sons <01121> [but thou.]
