How old was Miriam when she died?

[tonychanyt]

Moses led the Israelites 40 years in the wilderness (De 29:5).

Numbers 20:

1 And the people of Israel, the whole congregation, came into the wilderness of Zin in the first month, and the people stayed in Kadesh. And Miriam died there and was buried there.

Miriam died in the 1st month of the 40th year in the wilderness.

4 months later, Nu 33:

38 And Aaron the priest went up Mount Hor at the command of the LORD and died there, in the fortieth year after the people of Israel had come out of the land of Egypt, on the first day of the fifth month. 39 And Aaron was 123 years old when he died on Mount Hor.

A few more months later, Deuteronomy 34:

7 Moses was a hundred and twenty years old when he died.

Roughly speaking, Moses died a year after Miriam.

How old was Miriam when her brother (Moses) was born?

Ex 2:

1 Now a man from the house of Levi went and took as his wife a Levite woman. 2The woman conceived and bore a son, and when she saw that he was a fine child, she hid him three months. 3 When she could hide him no longer, she took for him a basket made of bulrushes and daubed it with bitumen and pitch. She put the child in it and placed it among the reeds by the river bank.

Moses was 3 months old when Miriam spoke to Pharaoh's daughter.

4 And his sister stood at a distance to know what would be done to him. 5 Now the daughter of Pharaoh came down to bathe at the river, while her young women walked beside the river.

She saw the basket among the reeds and sent her servant woman, and she took it. 6 When she opened it, she saw the child, and behold, the baby was crying. She took pity on him and said, “This is one of the Hebrews’ children.” 7 Then his sister said to Pharaoh’s daughter, “Shall I go and call you a nurse from the Hebrew women to nurse the child for you?” 8 And Pharaoh’s daughter said to her, “Go.” So the girl went and called the child’s mother.

young woman (ripe sexually; maid or newly married).

Let's say that Miriam was 12 years old at this time. Then she died at 12+120-1 = 131.
