Old Testament: Daniel, because of its descriptions of Jesus as Ancient of Days and it’s application to today
Duterocanon: either Wisdom of Solomon for its poetry, or 4 Ezra for its trippy visuals and for supposedly inspiring Columbus to look for America
New Testament: 1 Corinthians for the Love passage
Pseudoapigrapha: some of the Nag Hammadi stuff, although heresy, is beautiful in its poetry (Thunder Perfect Mind is a good example)
