'Ridge' in the Bible

They got up early the next morning and went up the ridge of the hill country, saying, “Let’s go to the place the Lord promised, for we were wrong.”

But they dared to go up the ridge of the hill country, even though the ark of the Lord’s covenant and Moses did not leave the camp.

So David and his men proceeded along the road as Shimei was going along the ridge of the hill opposite him. As Shimei went, he cursed David, and threw stones and dirt at him.
