Moses has Aaron tell the people to ‘come near to God’ because from the very beginning what God wants, what God desires from the Israelites and from us is a relationship. The Glory of God that was ever present with them in the wilderness, a cloud in the daylight and a ball of fire at night. It was a constant visual reminder that God was, quite literally with them.
11-12 God spoke to Moses, "I've listened to the complaints of the Israelites. Now tell them: 'At dusk you will eat meat and at dawn you'll eat your fill of bread; and you'll realize that I am God, your God.'" 13-15 That evening quail flew in and covered the camp and in the morning there was a layer of dew all over the camp. When the layer of dew had lifted, there on the wilderness ground was a fine flaky something, fine as frost on the ground. The Israelites took one look and said to one another, man-hu (What is it?). They had no idea what it was. 15-16 So Moses told them, "It's the bread God has given you to eat. And these are God's instructions: 'Gather enough for each person, about two quarts per person; gather enough for everyone in your tent.'" 19 Moses said to them, "Don't leave any of it until morning." 20 But they didn't listen to Moses. A few of the men kept back some of it until morning. It got wormy and smelled bad. 31 The Israelites named it manna (What is it?). It looked like coriander seed, whitish. And it tasted like a cracker with honey. 32 Moses said, "This is God's command: 'Keep a two-quart jar of it, an omer, for future generations so they can see the bread that I fed you in the wilderness after I brought you out of Egypt.'" 35 The Israelites ate the manna for forty years until they arrived at the land where they would settle down. They ate manna until they reached the border into Canaan.
