For it involved a transition from the simple nomadic relations to those of the agricultural and more highly civilized Canaanite life.
The last and most characteristic festival of Canaanite life was that of Asiph or " ingathering " which after the Deuteronomic reformation (621 B.C.) had made a single sanctuary and therefore a considerable journey with a longer stay necessary, came to be called Succoth or booths.
Now when the Hebrews succeeded to these agricultural conditions and acquired possession of the Canaanite abodes, they naturally fell into the same cycle of religious ideas and tradition.
