SB 4.17.15
tam anvadhavat tad vainyah
kupito ’tyaruneksanah
saram dhanusi sandhaya
yatra yatra palayate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Seeing this, Maharaja Prthu became very angry, and his eyes became as red as the early-morning sun. Placing an arrow on his bow, he chased the cow-shaped earth wherever she would run.
