SB 10.68.19
tam sangamya yatha-nyayam
gam arghyam ca nyavedayan
tesam ye tat-prabhava-jñah
pranemuh sirasa balam
Translation:
They approached Lord Balarama and worshiped Him with gifts of cows and arghya, as was fitting. Those among the Kurus who understood His true power bowed down to Him, touching their heads to the ground.
Purport:
The acaryas explain that even the elders, like Bhismadeva, also bowed down to Lord Baladeva.
