'Mountains' in the Bible

Then the sons of the prophets said to Elisha, “Since there are 50 strong men here with your servants, please let them go and search for your master. Maybe the Spirit of the Lord has carried him away and put him on one of the mountains or into one of the valleys.”He answered, “Don’t send them.”

By thy messengers thou hast reproached the Lord, and hast said, With the multitude of my chariots I am come up to the height of the mountains, to the sides of Lebanon, and will cut down the tall cedar trees thereof, and the choice fir trees thereof: and I will enter into the lodgings of his borders, and into the forest of his Carmel.
