'Nether' in the Bible

And she said, Give me a blessing; for that thou hast set me in the land of the South, give me also springs of water. And he gave her the upper springs and the nether springs.

and it went down westward to the border of the Japhletites, unto the border of Beth-horon the nether, even unto Gezer; and the goings out thereof were at the sea.

And the border passed along from thence to Luz, to the side of Luz (the same is Beth-el), southward; and the border went down to Ataroth-addar, by the mountain that lieth on the south of Beth-horon the nether.
