Now the Hebrew dialect, like all the rest, has certain properties, consisting in a mode of speech which exhibits the national character. Dialect is accordingly defined as a style of speech produced by the national character. But prophecy is not marked by those dialects. For in the Hellenic writings, what are called changes of figures purposely produce obscurations, deduced after the style of our prophecies. But this is effected through the voluntary departure from direct speech which takes place in metrical or offhand diction. A figure, then, is a form of speech transferred from what is literal to what is not literal, for the sake of the composition, and on account of a diction useful in speech.
