From Easton's 1897 Bible Dictionary :
Booth a hut made of the branches of a tree. In such tabernacles Jacob sojourned for a season at a place named from this circumstance Succoth (Gen. 33:17). Booths were erected also at the feast of Tabernacles (q.v.), Lev. 23:42, 43, which commemorated the abode of the Israelites in the wilderness.
