One major form preserves the original words within a new sentence or poem. The author need not invent a new scriptural meaning or distort the recognized wording.
Two contexts remain analytically distinct: the passage's setting in its original source and the effect it acquires in the new composition. Familiar words can recall their source while contributing to the local meaning and sound of the new text.
Recognition alone is not proof of a particular source; the alleged origin should still be checked.
