'Cover' in the Bible

You will defeat every fortified city and every important city. You must chop down every productive tree, stop up all the springs, and cover all the cultivated land with stones."

They destroyed the cities, and each of them threw stones to cover every good piece of land. They stopped up every spring of water and cut down every good tree. In the end, only the buildings of Kir-hareseth were left. Then men with slings surrounded the city and attacked it.

On the following day, he took the cover and dipped it in water and spread it on his face, so that he died. And Hazael became king in his place.

But Jehoiada the priest took a chest, and making a hole in the cover of it, put it by the altar, on the right side when one comes into the house of the Lord; and the priests who kept the door put in it regularly all the money which was taken into the house of the Lord.
