Udyoga-parva 10
ऊचुश्न सर्वे देवेशं विष्णु वृत्रभयार्दिता: । त्रयो लोकास्त्वया क्रान्तास्त्रिभिर्विक्रमणै: पुरा
All the gods, tormented by fear of Vṛtrāsura, spoke to Viṣṇu, Lord of the gods, in this way: “O Lord, in former times you traversed and measured the entire threefold world with your three strides.”
