Why did Hashem instruct Moshe to see the land before he died?
Rashi (on Pasuk 52): Because Hashem knew how precious the land was in his eyes' (in which case, seeing it would give him great joy and satisfaction).
Seforno: In order to bestow his blessings upon it. 1
Da'as Zekenim (52), Hadar Zekenim (52), Rosh (44): Hashem could not grant his request to enter, so He granted his request to see it, lest He turn him away empty.
Targum Yonasan: Refer to 32:52:2:2.
Which is what Moshe intended when he initially asked for permission to see Eretz Yisrael - See, 3:24.
