Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 24

Sanskrit:

ये च दिग्विजये तस्य सन्नतिं न ययुर्नृपा: ।प्रसह्य रुद्धास्तेनासन्नयुते द्वे गिरिव्रजे ॥ २४ ॥

ITRANS:

ye ca dig-vijaye tasyasannatiṁ na yayur nṛpāḥprasahya ruddhās tenāsannayute dve girivraje

Translation:

Twenty thousand kings who had refused to submit absolutely to Jarāsandha during his world conquest had been forcibly imprisoned by him in the fortress named Girivraja.

Purport:

Śrīla Viśvanātha Cakravartī points out that these kings refused the payment of tribute and other forms of submission to Jarāsandha. Also, there is a well-known account in the Mahābhārata and other literatures that Jarāsandha desired to worship Mahā-bhairava by offering him the lives of one hundred thousand kings in sacrifice.
