SB 10.86.53
brahmano janmana sreyan
sarvesam praninam iha
tapasa vidyaya tustya
kim u mat-kalaya yutah
Translation:
By his very birth, a brahmana is the best of all living beings in this world, and he becomes even more exalted when he is endowed with austerity, learning and self-satisfaction, what to speak of devotion to Me.
