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.

764. Verse 13 On that very day Noah went in, and Shem and Ham and Japheth, Noah's sons, [and Noah's wife,] and the three wives of his sons with them, into the ark.

'They went into the ark' means here, as previously, that they were saved. 'Noah' means what belonged to that Church. 'Shem, Ham, and Japheth' means what belonged to the Churches that derived from it. 'The sons of Noah' means matters of doctrine. ['Noah's wife means the Church itself.] 'The three wives of his sons with them' means the derivative Churches themselves.
