14 And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, 15 and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so (Gen 1:14-15).the lampstand also for the light, with its utensils and its lamps, and the oil for the light (Exod 35:14)the lampstand of pure gold and its lamps with the lamps set and all its utensils, and the oil for the light (Exod 39:37).
32 And there shall be six branches going out of its sides, three branches of the lampstand out of one side of it and three branches of the lampstand out of the other side of it…37 You shall make seven lamps for it. And the lamps shall be set up so as to give light on the space in front of it (Exod 25:32,37).
