Bhagavad Gita 7.8

रसोऽहमप्सु कौन्तेय प्रभास्मि शशिसूर्ययोः।प्रणवः सर्ववेदेषु शब्दः खे पौरुषं नृषु ॥७.८॥

raso’hamapsu kaunteya prabhāsmi śaśisūryayoḥpraṇavaḥ sarvavedeṣu śabdaḥ khe pauruṣaṃ nṛṣu

I am the flavor in water, O Arjuna; I am the light in the moon and the sun; I am the syllable Om in all the Vedas, sound in the ether and virility in men.
