Translation: 

 

Sukadeva Gosvami said: From the sound of their voices, their physical stature and the marks of bowstrings on their forearms, Jarasandha could tell that his guests were of the royal order. He began to think he had seen them somewhere before.

 

Purport: 

 

The acaryas point out that Jarasandha had seen Lord Krsna, Bhimasena and Arjuna at Draupadi’s svayamvara ceremony. Since they had come begging in the guise of brahmanas, Jarasandha thought they must be low-class ksatriyas, as indicated here by the word rajanya-bandhun.
