Deuteronomy 29:8

And we took their land
Which belonged to the two kings, the lands of Jazer, Gilead, and Bashan, fine countries for pasturage:

and gave it for an inheritances unto the Reubenites, and to the
Gadites, and to the half tribe of Manasseh;
who requested it, and to whom it was granted on certain conditions, and they were now in possession of it; see ( Numbers 32:1-42 ) .
