'Spring' in the Bible

He went out to the spring and threw the salt in. Then he said, "This is what the Lord says, 'I have purified this water. It will no longer cause death or fail to produce crops."

They tore down the cities and each man threw a stone into every cultivated field until they were covered. They stopped up every spring and chopped down every productive tree. Only Kir Hareseth was left intact, but the slingers surrounded it and attacked it.
