SB 7.1.39

evam saptau sva-bhavanat
 patantau tau krpalubhih
proktau punar janmabhir vam
 tribhir lokaya kalpatam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
While Jaya and Vijaya, thus cursed by the sages, were falling to the material world, they were addressed as follows by the same sages, who were very kind to them. “O doorkeepers, after three births you will be able to return to your positions in Vaikuntha, for then the duration of the curse will have ended.”
