SB 8.18.17
tasma ity upanitaya
yaksa-rat patrikam adat
bhiksam bhagavati saksad
umadad ambika sati
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When Vamanadeva had thus been given the sacred thread, Kuvera, King of the Yaksas, gave Him a pot for begging alms, and mother Bhagavati, the wife of Lord Siva and most chaste mother of the entire universe, gave Him His first alms.
