John Gill Commentary Deuteronomy 3:27

"Get thee up unto the top of Pisgah, and lift up thine eyes westward, and northward, and southward, and eastward, and behold with thine eyes: for thou shalt not go over this Jordan." — Deuteronomy 3:27 (ASV)

Get thee up into the top of Pisgah
Which was the highest eminence of Mount Nebo, and so a very proper place to take a prospect from; see (Deuteronomy 32:49) (34:1)

and lift up thine eyes westward, and northward, and southward, and
eastward ;
to all the four points of the heaven, and to all the four quarters and borders of the land of Canaan:

and behold it with thine eyes ;
even the land of Canaan, and particularly Lebanon, though it lay to the north of it, that mountain he had such a desire to see. Moses, though old, his natural sight was very strong, and not in the least dim; and it is not improbable that it might be more than ordinarily increased and assisted at this time:

for thou shall not go over this Jordan ;
into the land of Canaan; this affair, of not being suffered to enter there, Moses frequently takes notice of, no less than four or five times, it being what lay near his heart.
