Bg 11.39

vāyur yamo ’gnir varuṇaḥ śaśāṅkaḥ
prajāpatis tvaṁ prapitāmahaś ca
namo namas te ’stu sahasra-kṛtvaḥ
punaś ca bhūyo ’pi namo namas te

Word for word: 

vāyuḥ — air; yamaḥ — the controller; agniḥ — fire; varuṇaḥ — water; śaśa–aṅkaḥ — the moon; prajāpatiḥ — Brahmā; tvam — You; prapitāmahaḥ — the great-grandfather; ca — also; namaḥ — my respects; namaḥ — again my respects; te — unto You; astu — let there be; sahasra–kṛtvaḥ — a thousand times; punaḥ ca — and again;bhūyaḥ — again; api — also; namaḥ — offering my respects; namaḥ te — offering my respects unto You.

Translation: 

You are air, and You are the supreme controller! You are fire, You are water, and You are the moon! You are Brahmā, the first living creature, and You are the great-grandfather. I therefore offer my respectful obeisances unto You a thousand times, and again and yet again!

 

So Arjuna is saying whatever the manifestation of power in this world ultimately they are manifestation of Supreme Lord or Vibhuti of Supreme Lord, Lords power are manifested through them.
