Genesis 1:17-19

Young's Literal Translation

¹⁷ and God giveth them in the expanse of the heavens to give light upon the earth,

¹⁸ and to rule over day and over night, and to make a separation between the light and the darkness; and God seeth that [it is] good;

¹⁹ and there is an evening, and there is a morning -- day fourth.
