SB 10.61.20
sri-rajovaca
katham rukmy ari-putraya
pradad duhitaram yudhi
krsnena paribhutas tam
hantum randhram pratiksate
etad akhyahi me vidvan
dvisor vaivahikam mithah
Translation:
King Pariksit said: How could Rukmi give his daughter to his enemy’s son? After all, Rukmi had been defeated by Lord Krsna in battle and was waiting for an opportunity to kill Him. Please explain this to me, O learned one — how these two inimical parties became united through marriage.
