The verb zun means to nourish, feed, or sustain — to provide the food and nutrition needed for life. It is related to mazon (food/nourishment). Though rare in the Hebrew Bible, the concept of divine nourishment saturates the Scriptures. God is the ultimate provider who sustains all living things with food and life.
The concept of divine nourishment runs throughout Scripture: God rained manna in the wilderness (Exodus 16), sustained Elijah through ravens (1 Kings 17), and feeds all creatures in their due season (Psalm 104:27–28; 145:15–16). Jesus declares himself the Bread of Life (John 6:35) — the one who truly nourishes the soul for eternal life. Every act of eating is, theologically, an acknowledgment of dependence on God, the great sustainer of life.
