The Bible refers to the Lord in many different ways seemingly interchangeably. Understood in the internal sense, though, there are important differences. To some degree, the meanings all start with "Jehovah," which is the Lord's actual name. It represents the perfect, eternal, infinite love which is the Lord's actual essence. As such it also represents the good will that flows from the Lord to us and His desire for us to be good. "God," meanwhile, represents the wisdom of the Lord and the true knowledge and understanding He offers to us. The term "the Lord" is very close in meaning to "Jehovah," and in many cases is interchangeable (indeed, translators have a tendency to go back and forth). When the two are used together, though, "the Lord" refers to the power of the Lord's goodness, the force it brings, whereas "Jehovah" represents the goodness itself. In the New Testament, the name "Jehovah" is never used; the term "the Lord" replaces it completely. There are two reasons for that. First, the Jews of the day considered the name "Jehovah" too holy to speak or write. Second, they would not have been able to grasp the idea that the Lord -- who was among them in human form at the time -- was in fact Jehovah Himself. This does ultimately lead to a difference in the two terms by the end of the Bible. Thought of as "Jehovah," the Lord is the ultimate human form and has the potential for assuming a physical human body; thought of as "the Lord" He actually has that human body, rendered divine by the events of his physical life.

The Lord's love is the sun of heaven, and it is natural for us to look above ourselves to the sun of this world in thinking about the Lord. It follows, then, that to be closer to the Lord we would climb into the highest places -- and indeed, people have been worshiping on mountains for ages. In fact, even steeples on modern churches are symbolic mountains. It makes sense, then, that a mountain in the Bible represents love to the Lord, the highest, purest love we human beings can experience. Mountains can also represent the desire for good that comes from the love of the Lord. Hills, meanwhile, represent a love of other people and a caring for them, and when "mountains" is used in the plural it generally represents both loves.
