Albert Barnes Commentary Deuteronomy 34:1

"And Moses went up from the plains of Moab unto mount Nebo, to the top of Pisgah, that is over against Jericho. And Jehovah showed him all the land of Gilead, unto Dan," — Deuteronomy 34:1 (ASV)

Dan - This can hardly be the Dan (Dan-Laish) of Judges 18:27 and following, which was not in Gilead. It is probably a town of this name which stood in the north of Peraea; perhaps the same as Dan-jaan (2 Samuel 24:6); and the Dan of Genesis 14:14.
