Numbers 27:12 - The Popular Commentary by Paul E. Kretzmann

And the Lord said unto Moses, Get thee up into this Mount Abarim, the range which runs parallel to the Jordan and the Dead Sea, the highest point of which, in that section which bore the name Pisgah, was Mount Nebo, from which Moses later viewed the Land of Promise, Deuteronomy 32:48-52, and see the land which I have given unto the children of Israel. This announcement was made at this time in order to remind Moses that his career was near its close and that he must prepare both himself and the people whom he had led thus far for his death, providing for their welfare and consecrating his successor.
