'Wagons' in the Bible

David rose up early in the morning, and left the sheep with a keeper, and took, and went, as Jesse had commanded him; and he came to the place of the wagons, as the army which was going forth to the fight shouted for the battle.

David arose, and came to the place where Saul had encamped; and David saw the place where Saul lay, and Abner the son of Ner, the captain of his army: and Saul lay within the place of the wagons, and the people were encamped around him.

So David and Abishai came to the people by night: and, behold, Saul lay sleeping within the place of the wagons, with his spear stuck in the ground at his head; and Abner and the people lay around him.
