Targum sobre Naum 1:1

The burden [W. has shadow] of the cup of cursing which Nineveh is to be made to drink. First Jonah, son of Amitti, [W. inserts the prophet] of Gath Hepher, proph[e]sied against her, and she turned from her sins; and now that she sinned again, Nahum from the house of Koshi prophesied against her again, according as it is written in this record.
