Bhagavad Gita 1.18 — The Pandava allies sound
द्रुपदो द्रौपदेयाश्च सर्वशः पृथिवीपते। सौभद्रश्च महाबाहुः शङ्खान्दध्मुः पृथक्पृथक् ॥
drupado draupadeyāśca sarvaśaḥ pṛthivīpate | saubhadraśca mahābāhuḥ śaṅkhāndadhmuḥ pṛthakpṛthak ||
Meaning
O lord of the earth, Drupada, the sons of Draupadi and the strong-armed son of Subhadra all blew their conches, each on his own.
