Srimad Bhagavatam Canto 10, Chapter 71, Text 05

SB 10.71.5

sa vai durvisaho raja
 nagayuta-samo bale
balinam api canyesam
 bhimam sama-balam vina
 
Translation: 
 
The invincible King Jarasandha is as strong as ten thousand elephants. Indeed, other powerful warriors cannot defeat him. Only Bhima is equal to him in strength.
 
Purport: 
 
Sridhara Svami explains that the Yadavas were extremely eager to kill Jarasandha, and thus to caution them Sri Uddhava spoke this verse. Jarasandha’s death could come only at the hand of Bhima. Srila Visvanatha Cakravarti adds that Uddhava had previously deduced this from the Jyotir-raga and other astrological scriptures he had learned from his teacher Brhaspati.
