Numbers 7:8
four carts <05699 0702> [four wagons.]
Merarites ........... son <01121> [the sons.]
Though the Merarites were the most numerous, yet they had the greatest burden, namely, the boards, bars, pillars, and sockets, to carry, (ch. 4:31, 32, 48.) Therefore they had double the number of waggons to what the Gershonites had assigned them.
