And thou shalt rejoice before the LORD thy God, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates, and the stranger, and the fatherless, and the widow, that are among you, in the place which the LORD thy God hath chosen to place his name there.
Thou shalt rejoice before the Lord thy God ... It was a time of great public rejoicing, in which the servants were to have the privilege of participating. Indeed, the national festivals were holidays for the servants; and repeated injunctions are made that they share in the feast (cf. Deuteronomy 12:18).
