• rājanya-bandhavaḥ — relatives of kṣatriyas
  Compound. He calls them rājanya-bandhus, not brāhmaṇas — having seen through. But the disguise remains binding because of his vow.
• bhikṣitam — what is begged
  Accusative neuter past participle. Whatever is begged — open-ended, like Bali's commitment to Vāmana. Once the petition is registered, the king cannot retract.
• ātmānam — my own body, my own self
  Accusative. The vow extends even to self-gift. Cf. Bali offering his own head when no land remained. The verse rhymes Jarāsandha with Bali deliberately.
• dustyajam — impossible to give up
  Accusative neuter adjective. Most precious — yet promised. Kṣatriya vacana-dharma absolute: 'though impossible to give, I will give.'

A king who has vowed to give will give even if asked for his own body. Jarāsandha here speaks like Bali; the resemblance is deliberate, and the next two verses make the parallel explicit. Tragedy in this chapter is that the man's virtue is real — his cruelty toward 20,800 captive kings simply lies elsewhere.
