SB 3.16.17

brahmanyasya param daivam
 brahmanah kila te prabho
vipranam deva-devanam
 bhagavan atma-daivatam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Lord, You are the supreme director of the brahminical culture. Your considering the brahmanas to be in the highest position is Your example for teaching others. Actually You are the supreme worshipable Deity, not only for the gods but for the brahmanas also.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In the Brahma-samhita it is clearly stated that the Supreme Personality of Godhead is the cause of all causes. There are undoubtedly many demigods, the chiefs of whom are Brahma and Siva. Lord Visnu is the Lord of Brahma and Siva, not to speak of the brahmanas in this material world. As mentioned in Bhagavad-gita, the Supreme Lord is very favorable towards all activities performed according to brahminical culture, or the qualities of control of the senses and mind, cleanliness, forbearance, faith in scripture, and practical and theoretical knowledge. The Lord is the Supersoul of everyone. In Bhagavad-gita it is said that the Lord is the source of all emanations; thus He is also the source of Brahma and Siva.
