SB 10.59.33
tatra rajanya-kanyanam
sat-sahasradhikayutam
bhaumahrtanam vikramya
rajabhyo dadrse harih
Translation:
There Lord Krsna saw sixteen thousand royal maidens, whom Bhauma had taken by force from various kings.
Purport:
Srila Sridhara Svami provides evidence from the sage Parasara, as quoted in the Visnu Purana (5.29.31), to the effect that there were actually 16,100 royal maidens imprisoned in Bhauma’s palace:
kanya-pure sa kanyanam
sodasatulya-vikramah
satadhikani dadrse
sahasrani maha-mate
“Within the maidens’ quarters, O wise one, that Lord of unequaled prowess found 16,100 princesses.”
Another relevant verse from the Visnu Purana (5.29.9) is as follows:
deva-siddhasuradinam
nrpanam ca janardana
hrtva hi so ’surah kanya
rurodha nija-mandire
“The demon [Bhaumasura] kidnapped the unmarried daughters of demigods, siddhas, asuras and kings, O Janardana, and imprisoned them in his palace.”
