Srimad Bhagavatam Canto 10, Chapter 04, Text 09

SB 10.4.9

sa tad-dhastat samutpatya
 sadyo devy ambaram gata
adrsyatanuja visnoh
 sayudhasta-mahabhuja
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The child, Yoga-maya-devi, the younger sister of Lord Visnu, slipped upward from Kamsa’s hands and appeared in the sky as Devi, the goddess Durga, with eight arms, completely equipped with weapons.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Kamsa tried to dash the child downward against a piece of stone, but since she was Yoga-maya, the younger sister of Lord Visnu, she slipped upward and assumed the form of the goddess Durga. The word anuja, meaning “the younger sister,” is significant. When Visnu, or Krsna, took birth from Devaki, He must have simultaneously taken birth from Yasoda also. Otherwise how could Yoga-maya have been anuja, the Lord’s younger sister?
