PURPORT

Lord Krsna was also a younger cousin of Maharaja Yudhisthira as well as the intimate friend of Arjuna. But all the family members of the Pandavas knew Lord Krsna as the Supreme Personality of Godhead. The Lord, although conscious of His supreme position, always behaved in a humanly custom, and so He also bowed down before the dying Bhismadeva as if He were one of the younger brothers of King Yudhisthira.
