Srimad Bhagavatam Canto 06, Chapter 01, Text 37

SB 6.1.37

sri-suka uvaca
ity ukte yamadutais te
 vasudevokta-karinah
tan pratyucuh prahasyedam
 megha-nirhradaya gira
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sukadeva Gosvami continued: Being thus addressed by the messengers of Yamaraja, the servants of Vasudeva smiled and spoke the following words in voices as deep as the sound of rumbling clouds.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The Yamadutas were surprised to see that the Visnudutas, although polite, were hindering the rule of Yamaraja. Similarly, the Visnudutas were also surprised that the Yamadutas, although claiming to be servants of Yamaraja, the supreme judge of religious principles, were unaware of the principles of religious action. Thus the Visnudutas smiled, thinking, “What is this nonsense they are speaking? If they are actually servants of Yamaraja they should know that Ajamila is not a suitable candidate for them to carry off.”
