In plain words
The poet, to those who seek him: Dēvakī's own son, who, before the very faces of the kings standing guard [over Jayadratha] and sharing out the hours among them, fought with his weapon so that the hours of day seemed gone: that day he hid the sun with his discus, and there are those who saw him right beside Arjuna, who fought with his arrow so that Jayadratha's head rolled into a waste pit.
