וְנָתַתָּ֥ה מֵהֽוֹדְךָ֖ עָלָ֑יו לְמַ֣עַן יִשְׁמְע֔וּ כָּל־עֲדַ֖ת בְּנֵ֥י יִשְׂרָאֵֽל׃
און זאָלסט אַרױפֿטאָן פֿון דײַן גלאַנץ אױף אים, כּדי די גאַנצע עדה פֿון די קינדער פֿון ישׂראל זאָלן געהאָרכן.
Rashi
ונתתה מהודך עליו AND THOU SHALT PUT SOME OF THY GLORY UPON HIM — This refers to the shining of the skin of his countenance (see Exodus 34:29—30).
Ibn Ezra
Bestow some of your radiance. To give him honor before the entire people of Israel. So that the entire community of Bnei Yisroel will hear. For they already believe in you, and when they see you honor him they will honor him as well, because they will follow your deeds.
Sforno
ונתתה מהודך עליו, you are to confer upon him some of the aura of your regal authority while you are still alive, so that the people will get into the habit of treating him with respect.

מהודך SOME OF THY GLORY, and not all thy glory; consequently we learn from this: Moses’ face beamed like the sun, Joshua's face only like the moon (Sifrei Bamidbar 140:2; Bava Batra 75a).
