SB 8.10.1
sri-suka uvaca
iti danava-daiteya
navindann amrtam nrpa
yuktah karmani yattas ca
vasudeva-paranmukhah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: O King, the demons and Daityas all engaged with full attention and effort in churning the ocean, but because they were not devotees of Vasudeva, the Supreme Personality of Godhead, Krsna, they were not able to drink the nectar.
