The whole Israelite community set out from Elim and came to the Desert of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after they had come out of Egypt. 2 In the desert the whole community grumbled against Moses and Aaron. 3 The Israelites said to them, “If only we had died by the Lord’s hand in Egypt! There we sat around pots of meat and ate all the food we wanted, but you have brought us out into this desert to starve this entire assembly to death.”4 Then the Lord said to Moses, “I will rain down bread from heaven for you. The people are to go out each day and gather enough for that day. In this way I will test them and see whether they will follow my instructions. 5 On the sixth day they are to prepare what they bring in, and that is to be twice as much as they gather on the other days.”6 So Moses and Aaron said to all the Israelites, “In the evening you will know that it was the Lord who brought you out of Egypt, 7 and in the morning you will see the glory of the Lord, because he has heard your grumbling against him. Who are we, that you should grumble against us?” 8 Moses also said, “You will know that it was the Lord when he gives you meat to eat in the evening and all the bread you want in the morning, because he has heard your grumbling against him. Who are we? You are not grumbling against us, but against the Lord.”9 Then Moses told Aaron, “Say to the entire Israelite community, ‘Come before the Lord, for he has heard your grumbling.’”10 While Aaron was speaking to the whole Israelite community, they looked toward the desert, and there was the glory of the Lord appearing in the cloud.11 The Lord said to Moses, 12 “I have heard the grumbling of the Israelites. Tell them, ‘At twilight you will eat meat, and in the morning you will be filled with bread. Then you will know that I am the Lord your God.’”
Israel came out of Egypt only one and half month and yet they complained and grumbling against Moses and Aaron for they have no food, they so quickly forgot the goodness of God, they forgot they were slave at Egypt, but God is good, full of mercy and love, God gave them the food, evening and morning God supplied all their needs. God is their provider. God want all generation to know it is God’s grace to provide all their needs. v33-35.
Moses told them not to keep it until morning, v19, and yet some of the people did not listen. when Moses said v27 you will not find anything on the Sabbath day, don’t go out but some of the people still not believed what Moses said, they went out and found nothing, they failed to trust God, they feared they don’t have enough food, they did not believe God will provide all their needs. God is a good God, He always provides all our needs. Trust in Him alone.
