Bereshis 1:3-5

Orthodox Jewish Bible

³ And Elohim said, Let there be light: and there was light [Tehillim 33:6,9].

⁴ And Elohim saw the light, that it was tov (good); and Elohim divided the ohr (light) from the choshech (darkness).

⁵ And Elohim called the light Yom (Day), and the darkness He called Lailah (Night). And the erev (evening) and the boker (morning) were Yom Echad (Day One, the First Day, Mk 16:2).
