Deuteronomy 16:13

Thou shalt keep Heb. perform for thyself, see on Deuteronomy 16:1.

the feast of booths] feast, ḥag, as in Deuteronomy 16:10. Booths, suḳḳôth, lit. plaitingsor interlacings, whether natural thickets(Job 38:40, etc.) or artificial shelters of branches or planks, especially for the guardians of vineyards (Isaiah 1:8); applied first by D, and explained by H, Leviticus 23:39-43, which prescribes that the people shall dwell throughout the feast in booths of palm-fronds, boughs of thick trees and poplars (Nehemiah 8:15, olive, myrtle, palm and thick tree branches). H's reason for this custom is that Israel dwelt in booths at the Exodus; but the general resort of the cultivators to booths in their vineyards at the time of the ripening of the grapes and the vintage, which still continues in Palestine (Robinson, Bib. Res. ii. 81), was no doubt very ancient and the real origin of the name of the Feast. After the centralisation of the cultus, the booths were erected in the courts and on the flat roofs of the city, Nehemiah 8:14-17, which implies that before the restoration of Israel's worship under Nehemiah the custom had been in abeyance. The term tabernaclesis used in the EVV. in the sense given by Johnson of -casual dwellings" (Lat. tabernaa hut, tabernaculuma tent).
