Bhagwat Gita 4.13

chātur-varṇyaṁ mayā sṛiṣhṭaṁ guṇa-karma-vibhāgaśhaḥ

tasya kartāram api māṁ viddhyakartāram avyayam

Translation

The four categories of occupations were created by me according to people’s qualities and activities. Although I am the creator of this system, know me to be the non-doer and eternal.
