Reuben, Tribe of At the Exodus numbered 46,500 male adults, from twenty years old and upwards (Num 1:20, Num 1:21), and at the close of the wilderness wanderings they numbered only 43,730 (Num 26:7). This tribe united with that of Gad in asking permission to settle in the "land of Gilead," "on the other side of Jordan" (Num 32:1). The lot assigned to Reuben was the smallest of the lots given to the trans-Jordanic tribes.
