Numbers 2:12

And those which pitch by him shall be the tribe of Simeon ,.... Under his standard, and on one side of it; Reuben and Simeon being brothers by the mother as well as the father's side, might well be thought to agree together; and Reuben being the eldest brother, and the eldest of all Jacob's sons, Simeon would not grudge to pitch under him:

and the captain of the children of Simeon shall be Shelumiel the son of Zurishaddai ; of whom see Numbers 1:6 .
