SB 10.53.17

tatra śālvo jarāsandho
 dantavakro vidūrathaḥ
ājagmuś caidya-pakṣīyāḥ
 pauṇḍrakādyāḥ sahasraśaḥ
tatra — there; śālvaḥ jarāsandhaḥ dantavakraḥ vidūrathaḥ — Śālva, Jarāsandha, Dantavakra and Vidūratha; ājagmuḥ — came; caidya — of Śiśupāla; pakṣīyāḥ — taking the side; pauṇḍraka — Pauṇḍraka; ādyāḥ — and others; sahasraśaḥ — by the thousands.
Śiśupāla’s supporters — Śālva, Jarāsandha, Dantavakra and Vidūratha — all came, along with Pauṇḍraka and thousands of other kings.

Those familiar with the history of Lord Kṛṣṇa’s life will immediately recognize the names given in this text. The kings mentioned here maintained a deep animosity toward Śrī Kṛṣṇa and opposed Him in one way or another. But they were all to be frustrated and defeated on the occasion of Śiśupāla’s would-be wedding.
