Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Thereafter, on the day of soma-pana, after the sacrifice was finished, Garuda, king of the birds, understanding the desire of his master, arrested Bali Maharaja with the ropes of Varuna.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Garuda, the constant companion of the Supreme Personality of Godhead, knows the confidential part of the Lord’s desire. Bali Maharaja’s tolerance and devotion were undoubtedly superexcellent. Garuda arrested Bali Maharaja to show the entire universe the greatness of the King’s tolerance.
