Deuteronomy 16:14-17

BSB(i) 14 And you shall rejoice in your feast—you, your sons and daughters, your menservants and maidservants, and the Levite, as well as the foreigner, the fatherless, and the widows among you. 15 For seven days you shall celebrate a feast to the LORD your God in the place He will choose, because the LORD your God will bless you in all your produce and in all the work of your hands, so that your joy will be complete. 16 Three times a year all your men are to appear before the LORD your God in the place He will choose: at the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Tabernacles. No one should appear before the LORD empty-handed. 17 Everyone must appear with a gift as he is able, according to the blessing the LORD your God has given you.
