ר' יוסי בר' יהודה אומר: שלשה פרנסים טובים עמדו לישראל. אלו הן משה ואהרן ומרים. וג' מתנות טובות ניתנו על ידם ואלו הן באר וענן ומן. באר בזכות מרים עמוד ענן בזכות אהרן מן בזכות משה. מתה מרים נסתלק הבאר שנאמר (במדבר כ, א) ותמת שם מרים וכתיב בתריה ולא היה מים לעדה...
R. Yossi son of R. Judah says: Three good leaders had arisen for Israel, namely Moses, Aaron and Miriam, and for their sakes three good things were conferred [upon Israel], namely, the Well, the Pillar of Cloud, and the Manna.
The Well -- for the merit of Miriam;
The Pillar of Cloud --for the merit of Aaron;
The Manna -- for the merit of Moses.
When Miriam died the well disappeared, as it is said, "And Miriam died there," and immediately follows [the verse], "And there was no water for the congregation...."
(1) A certain man of the house of Levi went and married a Levite woman. (2) The woman conceived and bore a son; and when she saw how beautiful he was, she hid him for three months. (3) When she could hide him no longer, she got a wicker basket for him and caulked it with bitumen and pitch. She put the child into it and placed it among the reeds by the bank of the Nile. (4) And his sister stationed herself at a distance, to learn what would befall him. (5) The daughter of Pharaoh came down to bathe in the Nile, while her maidens walked along the Nile. She spied the basket among the reeds and sent her slave girl to fetch it. (6) When she opened it, she saw that it was a child, a boy crying. She took pity on it and said, “This must be a Hebrew child.” (7) Then his sister said to Pharaoh’s daughter, “Shall I go and get you a Hebrew nurse to suckle the child for you?” (8) And Pharaoh’s daughter answered, “Yes.” So the girl went and called the child’s mother.
(20) Then Miriam the prophetess, Aaron’s sister, took a timbrel in her hand, and all the women went out after her in dance with timbrels. (21) And Miriam chanted for them: Sing to the LORD, for He has triumphed gloriously; Horse and driver He has hurled into the sea.
(1) מרים הנביאה, “Miriam the prophetess;” the word “prophetess” is used here to describe Miriam’s extraordinary ability to use words to express her feelings. According to Rash’bam, the word is also used as describing someone who preaches to people to behave morally and ethically correctly. Compare when G-d told Moses that his brother Aaron would be נביאך, which can hardly mean: “your prophet,” as Moses outclassed him in that department.
(ב) בעשרה בו מתה מרים ונסתלק הבאר
(2) ....On the tenth of (Nisan) Miriam died and her well disappeared....
(א) ולא היה מים לעדה. על צד העונש חסרו המים לפי שלא הספידוה כראוי, כי במשה ואהרן נאמר ויבכו אותם בני ישראל וכאן לא נאמר ויבכו אותה ונאמר ותמת שם ותקבר שם, כי במקום שמתה שם תהא קבורתה לאלתר ונשכחה כמת מלב ולא הרגישו בהעדרה כלל ע"כ נחסרו להם המים כדי שידעו למפרע שהבאר היה בזכות מרים
"And there was not water for the congregation"
The people lacked water as a punishment because they did not mourn for her appropriately. The text tells us about Moses's and Aaron's deaths "the Children of Israel wept for them," and here, (in the story of Miriam's death), it doesn't say "they wept for her," and it does say, "She died there and they buried her there." In the place that she died, that will be her burial place forever, and she was forgotten as dead from the heart, and they did not feel her absence at all. Therefore, they lacked the water so that they should know retroactively that the well existed because of the merit of Miriam.
(1) The well in Miriam’s merit. For immediately after Miriam died they no longer had water. You might ask: Why was the well not in Aaron's or Moses's merit? The answer is that it was in the merit of Miriam waiting for Moses by the water, to see what would happen to him when he was placed there in the box [as a baby] (Exodus 2:4). In return, this merit of the well, i.e., the water that God provided for the congregation was on her behalf.
דרש רב עוירא בשכר נשים צדקניות שהיו באותו הדור נגאלו ישראל ממצרים
§ Rav Avira taught: In the merit of the righteous women that were in that generation, the Jewish people were redeemed from Egypt.
"Miriam's Cup" from RitualWell.org
A Miriam's Cup is a new ritual object that is placed on the seder table beside the Cup of Elijah. Miriam's Cup is filled with water. It serves as a symbol of Miriam's Well, which was the source of water for the Israelites in the desert. Putting a Miriam's Cup on your table is a way of making your seder more inclusive. It lets people know that at your table, the words of girls and boys, women and men, are welcome. It is also a way of drawing attention to the importance of Miriam and the other women of the Exodus story - women who have sometimes been overlooked...
There are many legends about Miriam’s Well. It is said to have been a magical source of water that followed the Israelites for 40 years because of the merit of Miriam. The waters of this well were said to be healing and sustaining. Thus, Miriam’s Cup is a symbol of all that sustains us through our own journeys, while Elijah’s Cup is a symbol of a future Messianic time.

Miriam's Song by Debbie Friedman
[Chorus]
And the women dancing with their timbrels
Followed Miriam as she sang her song
Sing a song to the One whom we've exalted
Miriam and the women danced and danced the whole night long
[Verse 1]
And Miriam was a weaver of unique variety
The tapestry she wove was one which sang our history
With every strand and every thread she crafted her delight
A woman touched with spirit, she dances toward the light
[Chorus]
And the women dancing with their timbrels
Followed Miriam as she sang her song
Sing a song to the One whom we've exalted
Miriam and the women danced and danced the whole night long
[Verse 2]
When Miriam stood upon the shores and gazed across the sea
The wonder of this miracle she soon came to believe
Whoever thought the sea would part with an outstretched hand
And we would pass to freedom and march to the promised land
[Chorus]
And the women dancing with their timbrels
Followed Miriam as she sang her song
Sing a song to the One whom we've exalted
Miriam and the women danced and danced the whole night long
[Verse 3]
And Miriam the prophet took her timbrel in her hand
And all the women followed her just as she had planned
And Miriam raised her voice in song, she sang with praise and might
We've just lived through a miracle, we're going to dance tonight
[Chorus]
And the women dancing with their timbrels
Followed Miriam as she sang her song
Sing a song to the One whom we've exalted
Miriam and the women danced and danced the whole night long
