Okay, so my Bible textbook this past semester pointed out that Hebrew poetry tends pastoral (Hill and Walton, A Survey of the Old Testament, 3rd ed). Now, having read a whole lot of Hebrew poetry this past semester, I think I'm capable of making that observation on my own, though I might not have if the text hadn't pointed it out at first. If I wanted to make the same general observation (probably using similar words; after all, how many different ways can you say that?), would I need a citation? What if I was only making the observation with regard to a specific poem, eg "Psalm 104 is a very pastoral work?" Thanks!
