Deuteronomy 16:13-17 - The Festival Of Booths
13 "You shall celebrate the Feast of Booths for yourselves seven days {at the gathering in of the produce} from your threshing floor and from your press; 14 and you shall rejoice at your feast, you and your son and your daughter and your slave and your slave woman and the Levite and the orphan and the widow that [are] in your {towns}. 15 Seven days you shall celebrate [your] feast to Yahweh your God at the place Yahweh will choose, for Yahweh your God shall bless you in all of your produce and in all [of] the work of your hand, and you shall surely [be] rejoicing.
16 Three times in the year all [of] your males shall appear {before } Yahweh your God at the place that he will choose, at the Feast of Unleavened Bread and at the Feast of Weeks and at the Feast of Booths, and they shall not appear {before Yahweh} empty-handed. 17 Each [person] {shall give as he is able}, [that is], according to the blessing of Yahweh your God that he has given to you.
