A more precise determination of the method of executing the order given in Numbers 2:17. The appointed place of the tabernacle, in the midst of the host, was represented during the march by the ark, the holy vessels, etc. carried by the Kohathites. The actual structure of the tabernacle was borne in advance by the Gershonites and Merarites, immediately behind the camp of Judah; so as to be set up ready against the arrival of the sacred utensils borne by the Kohathites. Compare Numbers. 2; 4,

And the tabernacle was taken down; and the sons of Gershon and the sons of Merari set forward, bearing (g) the tabernacle.
(g) With all the belongings of it.

And the tabernacle was taken down,.... By the Levites, as Aben Ezra, and which appears to be their work, from Numbers 1:51; this began to be done by them as soon as the cloud was perceived to move upwards, and the camp of Judah was preparing to march; and after Aaron and his sons had taken the holy vessels out of the holy and most holy place, and had packed up and covered them as directed, Numbers 4:5; this was an emblem of the taking down of the Jewish church state, the abolition of the service of the sanctuary, as well as of the changeable condition of the Gospel church in the wilderness, which is not always in one and the same place, but is moved from place to place, and that by the ministers of the word, signified by the Levites, who are sent and carry the Gospel here and there:
and the sons of Gershon and the sons of Merari set forward, bearing the tabernacle; the former, the hangings and vail, and the latter the boards, pillars, sockets, &c. each of them having wagons for their assistance: these followed immediately after the camp of Judah.
