Mandala 3, Hymn 33, Verse 1
प्र पर्व॑तानामुश॒ती उ॒पस्था॒दश्वे॑ इव॒ विषि॑ते॒ हास॑माने गावे॑व शु॒भ्रे मा॒तरा॑ रिहा॒णे विपा॑ट् छुतु॒द्री पय॑सा जवेते
"FORTH from the bosom of the mountains, eager as two swift mares with loosened rein contending, Like two bright mother cows who lick their youngling, Vipâṣ and Ṣutudrî speed down their waters."
