「BEULAH LAND」という題名は旧約聖書から来ている。

Thou shalt no more be termed Forsaken neither shall thy land any more be termed Desolate:
but thou shall be called Hephzibah, and thy land Beulah: for the Lord delighteth in thee, and
thy land shall be married. (Isaiah 62:4)

現代訳ならこうだ。
Your name will no longer be “Deserted and Childless”, but “Happily Married”. You will please
the Lord; your country will be his bride. Your people will take the land, just as a young man
takes a bride. The lord will be pleased because of you, just a husband is pleased with his bride.
