Mbh 13.156.1

"'Bhishma said, "Thus addressed, Arjuna remained silent. The god of wind once more addressed him, saying, 'Hear me, O foremost one of the Haihayas, as I narrate to thee the achievement of the high-souled Atri. Once on a time as the gods and Danavas were fighting each other in the dark, Rahu pierced both Surya and Soma with his arrows. The gods, overwhelmed by darkness, began to fall before the mighty Danavas, O foremost of kings! Repeatedly struck by the Asuras, the denizens of heaven began to lose their strength. They then beheld the learned Brahmana Atri, endued with wealth of penances, engaged in the observance of austerities. Addressing that Rishi who had conquered all his senses and in whom wrath had been extinguished, they said "Behold, O Rishi, these two, viz., Soma and Surya, who have both been pierced by the Asuras with their arrows! In consequence of this, darkness has overtaken us, and we are being struck down by the foe. We do not see the end of our troubles! Do thou, O lord of great puissance, rescue us from this great fear."
