Srila Visvanatha Cakravarti quotes the following verses from Sri Padma Purana, Uttara-khanda, to describe how Lord Krishna transferred the citizens from Mathura to Dvaraka:
sushuptan mathurayan tu
paurams tatra janardanah
uddhritya sahasa ratrau
dvarakayam nyavesayat
prabuddhas te janah sarve
putra-dara-samanvitah
haima-harmya-tale vishta
vismayam paramam yayuh
"In the middle of the night, as the citizens of Mathura slept, Lord Janardana suddenly removed them from that city and placed them in Dvaraka. When the men awoke, they were all amazed to find themselves, their children and their wives sitting inside palaces made of gold."
Thus end the purports of the humble servants of His Divine Grace A. C. Bhaktivedanta Swami Prabhupada to the Tenth Canto, Fiftieth Chapter, of the Srimad-Bhagavatam, entitled "Krishna Establishes the City of Dvaraka."
