An encampment is the temporary resting place of an army or company of travelers, and by extension may refer to the army or caravan while it is on the march.
Israel’s camp was centered on the tabernacle. The tribes were arranged in four divisions according to their standards, while Moses, Aaron, the priests, and the Levites camped around the sanctuary. This order was preserved during travel.
The tabernacle occupied the central position, corresponding to the chief’s tent in an ordinary encampment. The cloudy or fiery pillar served as the distinguishing sign over the central camp.
