SB 9.6.28
utthitas te nisamyatha
vyudakam kalasam prabho
papracchuh kasya karmedam
pitam pumsavanam jalam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When the brahmanas got up from bed and saw the waterpot empty, they inquired who had done this work of drinking the water meant for begetting a child.
