Deuteronomy 16:15-17

Darby Translation

¹⁵ Seven days shalt thou hold a feast to Jehovah thy God in the place which Jehovah will choose; for Jehovah thy God will bless thee in all thy produce, and in all the work of thy hands, and thou shalt be wholly joyful.

¹⁶ Three times in the year shall all thy males appear before Jehovah thy God in the place which he will choose, at the feast of unleavened bread, and at the feast of weeks, and at the feast of tabernacles; and they shall not appear before Jehovah empty:

¹⁷ each [shall give] according to that which is in his power to give, according to the blessing of Jehovah thy God which he hath given thee.
