In the tabernacle, God set up 2 things within His house. One was a table with bread on it. The other was a lampstand. God needs neither food nor lamps, but He has shaped His house to our needs so that we can live with Him according to our frame. He has provided His Son, bread from heaven, and so we eat bread. Jesus is also the light of the world. He is the dawn. We need light to eat by, to be able to tell if the food is cooked and clean. We can trust Jesus to give good light and good food both. He not only saves, He sustains. One thing about food and light, we need both moment by moment. Without the sun we will freeze within minutes. Without food we will starve within days. Jesus sustains our needy souls with fresh supplies of light and bread.
