Chagigah

Mishnah:

All are obligated in “the appearing” [i.e. making a pilgrimage on the major holidays to the Temple], except a deaf man, a mentally ill person, and a child, and one of doubtful gender, and one of double gender, and women, and slaves who are not freed, the lame man, and the blind man, and the sick man, and the old man, and he who is not able to go up on his feet.

What is the definition of a child? One who is not able to ride upon his father’s shoulders, and to go up from Jerusalem to the mountain of the Temple. These are the words of the house of Shammai. But the house of Hillel say, Anyone who is not able to take hold of his father’s hand, and to go up from Jerusalem to the mountain of the House, as it is said, (Exodus 23:14) “three times.”

The house of Shammai say, The “appearing” involves two pieces of silver and the hagigah a meah of silver, but the house of Hillel say, The “appearing” involves a meah of silver and the hagigah two pieces of silver.
