Srimad Bhagavatam Canto 10, Chapter 84, Text 47

SB 10.84.47

tam abhyasiñcan vidhi-vad
 aktam abhyaktam rtvijah
patnibhir asta-dasabhih
 soma-rajam ivodubhih
 
Translation: 
 
After Vasudeva’s eyes had been decorated with black cosmetic and his body smeared with fresh butter, the priests initiated him according to scriptural rules by sprinkling him and his eighteen wives with sacred water. Encircled by his wives, he resembled the regal moon encircled by stars.
 
Purport: 
 
Devaki was Vasudeva’s principal wife, but she had several co-wives, including her six sisters. This fact is recorded in the Ninth Canto of Srimad-Bhagavatam:
 
devakas cograsenas ca
 catvaro devakatmajah
devavan upadevas ca
 sudevo devavardhanah
 
tesam svasarah saptasan
 dhrtadevadayo nrpa
santidevopadeva ca
 srideva devaraksita
sahadeva devaki ca
 vasudeva uvaha tah
 
“Ahuka had two sons, named Devaka and Ugrasena. Devaka had four sons, named Devavan, Upadeva, Sudeva and Devavardhana, and he also had seven daughters, named Santideva, Upadeva, Srideva, Devaraksita, Sahadeva, Devaki and Dhrtadeva. Dhrtadeva was the eldest. Vasudeva, the father of Krsna, married all these sisters.” (Bhag. 9.24.21-23)
 
Some of Vasudeva’s other wives are mentioned a few verses later:
 
pauravi rohini bhadra
 madira rocana ila
devaki-pramukhas casan
 patnya anakadundubheh
 
“Devaki, Pauravi, Rohini, Bhadra, Madira, Rocana, Ila and others were all wives of Anakadundubhi [Vasudeva]. Among them all, Devaki was the chief.” (Bhag. 9.24.45)
