'Extremity' in the Bible

And they rose up in the dusk to go to the camp of the Syrians; and they came to the extremity of the camp of the Syrians; and behold, there was no man there.

And those lepers came to the extremity of the camp; and they went into one tent, and ate and drank, and carried thence silver and gold, and garments, and went and hid it; and they came again, and entered into another tent, and carried thence, and went and hid it.
