'Season' in the Bible
As it was, that time of year was the season for the first fruits of the grape harvest. So they went to explore the land from the Wilderness of Zin to Rehob, and as far as the outskirts of Hamath.
"On the first day of your harvest season, you are to hold a sacred assembly when you present your first fruits during the Festival of Weeks. No servile work is to be done.
