This sermon is based on Exodus 15-16, which reads:
The Song of Moses
15 Then Moses and the Israelites sang this song to the Lord:
“I will sing to the Lord, for he has triumphed gloriously;
horse and rider he has thrown into the sea.
2 The Lord is my strength and my might,
and he has become my salvation;
this is my God, and I will praise him,
my father’s God, and I will exalt him.
3 The Lord is a warrior;
the Lord is his name.
4 “Pharaoh’s chariots and his army he cast into the sea;
his picked officers were sunk in the Red Sea.
5 The floods covered them;
they went down into the depths like a stone.
6 Your right hand, O Lord, glorious in power—
your right hand, O Lord, shattered the enemy.
7 In the greatness of your majesty you overthrew your adversaries;
you sent out your fury, it consumed them like stubble.
8 At the blast of your nostrils the waters piled up,
the floods stood up in a heap;
the deeps congealed in the heart of the sea.
9 The enemy said, ‘I will pursue, I will overtake,
I will divide the spoil, my desire shall have its fill of them.
I will draw my sword, my hand shall destroy them.’
10 You blew with your wind, the sea covered them;
they sank like lead in the mighty waters.
11 “Who is like you, O Lord, among the gods?
Who is like you, majestic in holiness,
awesome in splendor, doing wonders?
12 You stretched out your right hand,
the earth swallowed them.
13 “In your steadfast love you led the people whom you redeemed;
you guided them by your strength to your holy abode.
14 The peoples heard, they trembled;
pangs seized the inhabitants of Philistia.
15 Then the chiefs of Edom were dismayed;
trembling seized the leaders of Moab;
all the inhabitants of Canaan melted away.
16 Terror and dread fell upon them;
by the might of your arm, they became still as a stone
until your people, O Lord, passed by,
until the people whom you acquired passed by.
17 You brought them in and planted them on the mountain of your own possession,
the place, O Lord, that you made your abode,
the sanctuary, O Lord, that your hands have established.
18 The Lord will reign forever and ever.”
19 When the horses of Pharaoh with his chariots and his chariot drivers went into the sea, the Lord brought back the waters of the sea upon them; but the Israelites walked through the sea on dry ground.
The Song of Miriam
20 Then the prophet Miriam, Aaron’s sister, took a tambourine in her hand; and all the women went out after her with tambourines and with dancing. 21 And Miriam sang to them:
“Sing to the Lord, for he has triumphed gloriously;
horse and rider he has thrown into the sea.”
Bitter Water Made Sweet
22 Then Moses ordered Israel to set out from the Red Sea, and they went into the wilderness of Shur. They went three days in the wilderness and found no water. 23 When they came to Marah, they could not drink the water of Marah because it was bitter. That is why it was called Marah. 24 And the people complained against Moses, saying, “What shall we drink?” 25 He cried out to the Lord; and the Lordshowed him a piece of wood; he threw it into the water, and the water became sweet.
There the Lord made for them a statute and an ordinance and there he put them to the test. 26 He said, “If you will listen carefully to the voice of the Lord your God, and do what is right in his sight, and give heed to his commandments and keep all his statutes, I will not bring upon you any of the diseases that I brought upon the Egyptians; for I am the Lord who heals you.”
27 Then they came to Elim, where there were twelve springs of water and seventy palm trees; and they camped there by the water.
Bread from Heaven
16 The whole congregation of the Israelites set out from Elim; and Israel came to the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after they had departed from the land of Egypt. 2 The whole congregation of the Israelites complained against Moses and Aaron in the wilderness. 3 The Israelites said to them, “If only we had died by the hand of the Lord in the land of Egypt, when we sat by the fleshpots and ate our fill of bread; for you have brought us out into this wilderness to kill this whole assembly with hunger.”
4 Then the Lord said to Moses, “I am going to rain bread from heaven for you, and each day the people shall go out and gather enough for that day. In that way I will test them, whether they will follow my instruction or not. 5 On the sixth day, when they prepare what they bring in, it will be twice as much as they gather on other days.” 6 So Moses and Aaron said to all the Israelites, “In the evening you shall know that it was the Lord who brought you out of the land of Egypt, 7 and in the morning you shall see the glory of the Lord, because he has heard your complaining against the Lord. For what are we, that you complain against us?” 8 And Moses said, “When the Lord gives you meat to eat in the evening and your fill of bread in the morning, because the Lord has heard the complaining that you utter against him—what are we? Your complaining is not against us but against the Lord.”
9 Then Moses said to Aaron, “Say to the whole congregation of the Israelites, ‘Draw near to the Lord, for he has heard your complaining.’” 10 And as Aaron spoke to the whole congregation of the Israelites, they looked toward the wilderness, and the glory of the Lord appeared in the cloud. 11 The Lord spoke to Moses and said, 12 “I have heard the complaining of the Israelites; say to them, ‘At twilight you shall eat meat, and in the morning you shall have your fill of bread; then you shall know that I am the Lord your God.’”
13 In the evening quails came up and covered the camp; and in the morning there was a layer of dew around the camp. 14 When the layer of dew lifted, there on the surface of the wilderness was a fine flaky substance, as fine as frost on the ground. 15 When the Israelites saw it, they said to one another, “What is it?” For they did not know what it was. Moses said to them, “It is the bread that the Lordhas given you to eat. 16 This is what the Lord has commanded: ‘Gather as much of it as each of you needs, an omer to a person according to the number of persons, all providing for those in their own tents.’” 17 The Israelites did so, some gathering more, some less. 18 But when they measured it with an omer, those who gathered much had nothing over, and those who gathered little had no shortage; they gathered as much as each of them needed. 19 And Moses said to them, “Let no one leave any of it over until morning.” 20 But they did not listen to Moses; some left part of it until morning, and it bred worms and became foul. And Moses was angry with them. 21 Morning by morning they gathered it, as much as each needed; but when the sun grew hot, it melted.
22 On the sixth day they gathered twice as much food, two omers apiece. When all the leaders of the congregation came and told Moses, 23 he said to them, “This is what the Lord has commanded: ‘Tomorrow is a day of solemn rest, a holy sabbath to the Lord; bake what you want to bake and boil what you want to boil, and all that is left over put aside to be kept until morning.’” 24 So they put it aside until morning, as Moses commanded them; and it did not become foul, and there were no worms in it. 25 Moses said, “Eat it today, for today is a sabbath to the Lord; today you will not find it in the field. 26 Six days you shall gather it; but on the seventh day, which is a sabbath, there will be none.”
27 On the seventh day some of the people went out to gather, and they found none. 28 The Lord said to Moses, “How long will you refuse to keep my commandments and instructions? 29 See! The Lord has given you the sabbath, therefore on the sixth day he gives you food for two days; each of you stay where you are; do not leave your place on the seventh day.” 30 So the people rested on the seventh day.
31 The house of Israel called it manna; it was like coriander seed, white, and the taste of it was like wafers made with honey. 32 Moses said, “This is what the Lordhas commanded: ‘Let an omer of it be kept throughout your generations, in order that they may see the food with which I fed you in the wilderness, when I brought you out of the land of Egypt.’” 33 And Moses said to Aaron, “Take a jar, and put an omer of manna in it, and place it before the Lord, to be kept throughout your generations.” 34 As the Lord commanded Moses, so Aaron placed it before the covenant, for safekeeping. 35 The Israelites ate manna forty years, until they came to a habitable land; they ate manna, until they came to the border of the land of Canaan. 36 An omer is a tenth of an ephah.
