74:16 the light and the sun. Note that the “light” prepared by God is distinct from “the sun.” God first called for light energy, then light generators (Genesis 1:5, 14).
74:17 borders of the earth. God established both the boundaries of the lands and of the nations to occupy those lands, and even the inclination of the earth’s axis to control their seasons.
