“in the plains of Moab beyond the Jordan.” Moses alloted the land east of the Jordan to the Transjordan tribes while he was still alive. The event is not recorded in Scripture, but Moses was in the plains of Moab (Num. 26:3; 31:12; 33:49-50).

“beyond the Jordan, east of Jericho.” This tells us that Moses was encamped in the plains of Moab north of the Dead Sea, and east from Jericho.
