'Extremity' in the Bible

And they rise in the twilight, to go in unto the camp of Aram, and they come in unto the extremity of the camp of Aram, and lo, there is not a man there,

And these lepers come in unto the extremity of the camp, and come in unto one tent, and eat, and drink, and lift up thence silver, and gold, and garments, and go and hide; and they turn back and go in unto another tent, and lift up thence, and go and hide.

By the hand of thy messengers Thou hast reproached the Lord, and sayest: In the multitude of my chariots I have come up to a high place of mountains -- The sides of Lebanon, And I cut down the height of its cedars, The choice of its firs, And I enter the lodging of its extremity, The forest of its Carmel.
