Deuteronomy 16:15-17

Revised Standard Version

¹⁵ For seven days you shall keep the feast to the Lord your God at the place which the Lord will choose; because the Lord your God will bless you in all your produce and in all the work of your hands, so that you will be altogether joyful.

¹⁶ “Three times a year all your males shall appear before the Lord your God at the place which he will choose: at the feast of unleavened bread, at the feast of weeks, and at the feast of booths. They shall not appear before the Lord empty-handed; ¹⁷ every man shall give as he is able, according to the blessing of the Lord your God which he has given you.
