A figurative mode of discourse, which employs terms literally belonging to one thing, in order to express another. It is strictly a prolonged metaphor. Such are Nathan's address to David, 2 Samuel 12:1 - 14; Psalm 80:1-19 , and our Lord's parable of the sower, Luke 8:5 - 15 . The expression, "which things are an allegory," Galatians 4:24 , means that the events in the life of Isaac and Ishmael, mentioned in previous verses, have been allegorically applied.
Although written in 1859 by William Rand, this dictionary of the Bible from the American Tract Society is still relevant today.Wikipedia
