Sri Jambavati said: Unaware that Lord Krsna was none other than his own master and worshipable Deity, the husband of Goddess Sita, my father fought with Him for twenty-seven days. When my father finally came to his senses and recognized the Lord, he took hold of His feet and presented Him with both me and the Syamantaka jewel as tokens of his reverence. I am simply the Lord’s maidservant.
Jambavan had been Lord Ramacandra’s servant many thousands of years before. Srila Visvanatha Cakravarti mentions that while hearing Jambavati’s story, the women present recognized her as the girl whom Jambavan had once offered to Lord Sri Rama to be His wife. Since Lord Rama had taken a vow to have only one wife, He could not accept her then, but did so when He returned in the Dvapara-yuga as Krsna. The other queens wanted to honor Jambavati for this, but she replied humbly, “I am just the Lord’s maidservant.”
How Jambavati and Satyabhama became Lord Krsna’s wives is told in Chapter Fifty-six of the Tenth Canto.
