Deuteronomy 16:15-17

Young's Literal Translation

¹⁵ Seven days thou dost feast before Jehovah thy God, in the place which Jehovah doth choose, for Jehovah thy God doth bless thee in all thine increase, and in every work of thy hands, and thou hast been only rejoicing.

¹⁶ `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;

¹⁷ each according to the gift of his hand, according to the blessing of Jehovah thy God, which He hath given to thee.
