4.14.47

yadā vāmanarūpeṇa hṛtaṃ devena viṣṇunā |
tadaiva ca bhavatpautraḥ prokto devena jiṣṇunā ||

When the Lord of Vaikuntha had incarnated as Vâmana and stolen away the kingdom of Vali, then the Janârdan Visnu told Bali, the king of the Demons that “I have taken away your kingdom by pretext to serve the purpose of the Gods; you will become Indra, no doubt, in the coming Sâvarnika manvantara.”
