That exact phrase isn't used in the creation account. Something similar that is in Genesis 1:4 is:
ויבדל אלקים בין האור ובין החושך
This phrase means "God separated the light from the darkness" or "God separated between the light and the darkness"
The phrase you said would translate as "there is light in the darkness".
