Sloka:
Efforts by Lord Sri Krishna to avert the war failed.. War was imminent and both sides were preparing for it. A messenger from King Duryodhana came to King Jayadratha’s court to request him to participate in the war. 
 

O! Respected King of Sindhu, I am bowing before thee, who are the abode of valour and strength. I am a messenger sent by your brother-in-law, King Duryodhana.

The cunning Yadava (Krishna) came as an envoy from the son of Kunthi (Yudhishtira).

He requested that Duryidhana hand over half of his kingdom as a condition for peace.
