Joshua 12:6

‘ Moses the servant of YHWH, and the children of Israel, smote them, and Moses the servant of YHWH gave it for a possession to the Reubenites, and the Gadites, and the half tribe of Manasseh.'

For details of the smiting see Numbers 21:21. For the bestowal on the tribes see Numbers 32. The description of the activities under Moses, seen as to the glory of YHWH, is now completed.
