'Hills' in the Bible

Now the valley of Siddim was full of tar pits; and the kings of Sodom and Gomorrah fled, and they fell there, and those who remained fled to the hills.

The blessings of your father have prevailed above the blessings of your ancestors, above the boundaries of the ancient hills. They will be on the head of Joseph, on the crown of the head of him who is separated from his brothers.
