SB 6.3.34

ittham svabhartr-gaditam bhagavan-mahitvam
 samsmrtya vismita-dhiyo yama-kinkaras te
naivacyutasraya-janam pratisankamana
 drastum ca bibhyati tatah prabhrti sma rajan
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
After hearing from the mouth of their master about the extraordinary glories of the Lord and His name, fame and attributes, the Yamadutas were struck with wonder. Since then, as soon as they see a devotee, they fear him and dare not look at him again.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Since this incident, the Yamadutas have given up the dangerous behavior of approaching devotees. For the Yamadutas, a devotee is dangerous.
