Ramayana
यामि ज्ञात्वा कालमुपागतम् । ततो रुद्राः सहादित्या वसवो मरुतो ऽश्वनौ । सन्नद्धा निर्ययुस्तूर्णं राक्षसानभितः पुरात् ॥ 7-27-22 ॥
"I will go, when I know the time has come." Then the Rudras, together with the Adityas, the Vasus, the Maruts, and the two Ashvins, fully armed, swiftly marched forth from the city against the rakshasas on all sides.
