Mandatory Annual Pilgrimages

Deuteronomy 16:16-17

`Three times in a year doth every one of thy males appear before Jehovah thy God in the place which He doth choose--in the feast of unleavened things, and in the feast of weeks, and in the feast of booths; and they do not appear before Jehovah empty;

each according to the gift of his hand, according to the blessing of Jehovah thy God, which He hath given to thee.
