brahma-veṣa-dharo gatvā
taṁ bhikṣeta vṛkodaraḥ
haniṣyati na sandeho
dvai-rathe tava sannidhau
brahma - of a brāhmaṇa; veṣa - the dress; dharaḥ - wearing; gatvā - going; tam - to him, Jarāsandha; bhikṣeta - should beg; vṛka-udaraḥ - Bhīma; haniṣyati - he will kill him; na - no; sandehaḥ - doubt; dvai-rathe - in one-on-one chariot combat; tava - Your; sannidhau - in the presence.
The idea is that Bhīma should beg as charity a one-to-one fight with Jarāsandha.
