SB 8.18.29
sri-balir uvaca
svagatam te namas tubhyam
brahman kim karavama te
brahmarsinam tapah saksan
manye tvarya vapur-dharam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Bali Maharaja then said to Lord Vamanadeva: O brahmana, I offer You my hearty welcome and my respectful obeisances. Please let us know what we may do for You. We think of You as the personified austerity of the great brahmana-sages.
