ASV(i) 17 And the tabernacle was taken down; and the sons of Gershon and the sons of Merari, who bare the tabernacle, set forward. 18 And the standard of the camp of Reuben set forward according to their hosts: and over his host was Elizur the son of Shedeur. 19 And over the host of the tribe of the children of Simeon was Shelumiel the son of Zurishaddai. 20 And over the host of the tribe of the children of Gad was Eliasaph the son of Deuel.
21 And the Kohathites set forward, bearing the sanctuary: and [the others] did set up the tabernacle against their coming.
