The Book of Jubilees, also known as 'Little Genesis' or 'Kufale', is a pseudepigraphal text of the Old Testament that rewrites the history of Genesis and part of Exodus, with emphasis on the division of time into jubilees and weeks of years. It is canonical only in the Ethiopian Orthodox Tewahedo Church and preserved entirely in Ge'ez. The book was originally written in Hebrew around the 2nd century BC and is cited by the Early Church Fathers.
Jubilees
Chapter 47
And in the seventh week, in the seventh year, in the forty-seventh jubilee, your father went out from the land of Canaan, and you were born in the fourth week, in the sixth year, in the forty-eighth jubilee; this was the time of tribulation upon the children of Israel.
And Pharaoh, king of Egypt, issued a command concerning them that they should cast into the river all the male children that were born.
And they cast them for seven months until the day you were born, and your mother hid you for three months, and they spoke concerning her.
And she made an ark for you, and covered it with pitch and asphalt, and placed it among the reeds on the banks of the river, and she put you inside it for seven days, and your mother came at night and nursed you, and during the day Miriam, your sister, protected you from the birds.
And in those days Thermuthis, the daughter of Pharaoh, came to bathe in the river, and she heard your voice crying, and she sent her maids to bring you, and they brought you to her.
And she took you out of the ark, and had compassion on you.
And your sister said to her: "Shall I call for you one of the Hebrew women to nurse and rear this child for you? And she said: "Go."
And she went and called your mother Jochebed, and she gave her wages, and she nursed you.
And afterwards, when you were grown, they brought you to Pharaoh's daughter, and you became her son, and Amram your father taught you to write, and when you completed three weeks they brought you to the royal court.
And you were three weeks of years in the court until the time when you went out from the royal court and saw an Egyptian smiting your friend who was of the children of Israel, and you killed him and hid him in the sand.
And on the second day you found two of the children of Israel quarreling, and you said to him who was doing wrong: "Why do you strike your brother?"
And he was angry and indignant, and said: "Who made you a prince and a judge over us? Do you think to kill me as you killed the Egyptian yesterday?" And you feared and fled because of his words.
