Deuteronomy 16:15-17

Modern English Version

¹⁵ You are to celebrate the festival for seven days to the Lord your God in the place where the Lord will choose, because the Lord your God will bless you in all your produce, and in all the works of your hands. Therefore, you will indeed rejoice.

¹⁶ Three times a year all your males must appear before the Lord your God in the place where He will choose: at the Feast of Unleavened Bread, at the Feast of Weeks, and at the Feast of Tabernacles, and they must not appear before the Lord empty. ¹⁷ Every man must give as he is able, in proportion to the blessing of the Lord your God, which He has given you.
