'Mountain' in the Bible

Will I not, in that day, says the Lord, take away the wise men out of Edom, and wisdom out of the mountain of Esau?

And your men of war, O Teman, will be overcome with fear, so that every one of them may be cut off from the mountain of Esau.

For as you have been drinking on my holy mountain, so will all the nations go on drinking without end; they will go on drinking and the wine will go down their throats, and they will be as if they had never been.

And those who have been kept safe will come up from Mount Zion to be judges of the mountain of Esau; and the kingdom will be the Lord's.
