123:2.13

It was the custom of the Galilean Jews for the mother to bear the responsibility for a child’s training until the fifth birthday, and then, if the child were a boy, to hold the father responsible for the lad’s education from that time on. This year, therefore, Jesus entered upon the fifth stage of a Galilean Jewish child’s career, and accordingly on August 21, 2 B.C., Mary formally turned him over to Joseph for further instruction.
