Srimad Bhagavatam Canto 10, Chapter 30, Text 13

SB 10.30.13

prcchatema lata bahun
 apy aslista vanaspateh
nunam tat-karaja-sprsta
 bibhraty utpulakany aho
 
Translation: 
 
Let us ask these creepers about Krsna. Even though they are embracing the arms of their husband, this tree, they certainly must have been touched by Krsna’s fingernails, since out of joy they are manifesting eruptions on their skin.
 
Purport: 
 
The gopis reasoned that the creepers would not show signs of rapture merely by physical contact with their husband, a tree. Thus the gopis concluded that although the creepers were embracing the strong limbs of their husband, they must have been touched by Lord Krsna as He moved through the forest.
