The text for male children is taken from the blessing of Jacob (Gen. 48:20): "So he blessed them by saying ... God make you like Ephraim and Manasseh." To this was added the blessing for daughters: "May God make you like Sarah, Rebekah, Rachel and Leah." The Priestly Blessing is then recited in both cases. A personal prayer may also be added.
A further custom arose at the end of the Sabbath for children to be blessed again by their fathers and students by their teachers.
