Srimad Bhagavatam Canto 10, Chapter 13, Text 07

SB 10.13.7

tatheti payayitvarbha
vatsan arudhya sadvale
muktva sikyani bubhujuh
samam bhagavata muda
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Accepting Lord Krsna’s proposal, the cowherd boys allowed the calves to drink water from the river and then tied them to trees where there was green, tender grass. Then the boys opened their baskets of food and began eating with Krsna in great transcendental pleasure.
