신명기 10:21의 주석

HE IS THY PRAISE, AND HE IS THY G-D. The meaning thereof is that He should be your [sole object of] praise, that you are to devote all your praise to Him, praising Him always and not to give His glory to another, neither His praise to graven images,²⁶⁷Isaiah 42:8. nor to the gods and lords mentioned.²⁵⁶Exodus 32:9. Or he may be stating: “He is thy praise, for through Him you are praised above all peoples,” similar in expression to the verses, For Thou art the glory of their strength;²⁶⁸Psalms 89:18. O Eternal, my strength, and my stronghold.²⁶⁹Jeremiah 16:19. ”

היא תהלתך, your glory consists in the privilege of being a servant of a Being Who rules the entire cosmos.

הוא תהלתך, “He is your praise.” Nachmanides explains this to mean that whenever you feel that you want to praise someone you will praise Him. He is the only One worthy of praise. Another possible explanation is that when any other nation praises you, the Jewish people, it will always be in connection with and on account of your special relationship to Him.
