Is there a reference in the Old Testament to boys becoming a man as in the celebration of the Bar Mitzvah?

The Old Testament does not contain a specific reference to a celebration equivalent to the Bar Mitzvah, which marks a Jewish boy's coming of age at 13. However, the concept of a boy transitioning to manhood is implied in various passages, such as in Numbers 1:3, where men are counted from the age of 20 for military service. The formal celebration of Bar Mitzvah developed later in Jewish tradition, reflecting a community's recognition of a boy's responsibilities under Jewish law.
