taḿ dṛṣṭvācintayat kṛṣṇaḥ
sańkarṣaṇa sahāyavān
aho yadūnāḿ vṛjinaḿ
prāptaḿ hy ubhayato mahat
tam -- him; drishtva -- seeing; acintayat -- thought; krishnah -- Lord Krishna; sankarshana -- by Lord Balarama; sahaya-van -- assisted; aho -- ah; yadunam -- for the Yadus; vrijinam -- a problem; praptam -- arrived; hi -- indeed; ubhayatah -- from both sides (from Kalayavana and also from Jarasandha); mahat -- great.
We may note here that although Sri Krishna had defeated Jarasandha seventeen times against tremendous odds, He did not immediately annihilate the army of Kalayavana, thus keeping intact the benediction granted to Gargya by Lord Siva, as explained in the previous purport.
