'Spring' in the Bible

Then the border extended from the top of the mountain to the spring of the waters of Nephtoah and proceeded to the cities of Mount Ephron; then the border curved to Baalah (that is, Kiriath-jearim).

The southern side was from the edge of Kiriath-jearim, and the border went on westward and went to the source of the waters of Nephtoah.
