Translation of Genesis 1:5
God named light as day and named darkness as night. It was evening and it was morning of the first day.
God named Himself as light of day and darkness as night. It was evening and it was morning of the first day.
God called light. He will sleep and for darkness it was chosen night, and it was pleasing joining together. He was in calm, an then he will sleep alone. (a questionable translation)
Saying about evening and morning of the first day, it may be meant that it was the first day after the light appeared on the surface of the Earth (see Gen. 1:3).
God is light accordingly (1Jn. 1:5) "God is Light, and in Him there is no darkness at all". So God calls Himself light.
