The Levites Who Bore The Dwellingplace (Numbers 10:17)
‘And the tabernacle was taken down; and the sons of Gershon and the sons of Merari, who bore the tabernacle, set forward.'
Behind the leading troops set forward the sons of Gershon and Merari, the Levites who bore the Dwellingplace itself and all that was required for its erection. Once the cloud ceased moving they would immediately erect the Dwellingplace ready to receive the Sanctuary furniture.
