Proverbs 27, 14: He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.
It’s not just the passive-aggressive blessing that amuses me, but that it was a common enough problem that it was worth cursing. I have mixed feelings about Ecclesiastes, which does indeed have a large amount of recogniseable quotes of the “where are the snows of yesteryear” variety, but also a lot amount of repetition and occasional leaps into “and women are all evil whores who lead to hell”, although both of these are pretty much occupational hazards of reading the Old Testament, which taken as a whole (OK, the first 550 pages, I have 200 to go) is (a) dreadfully edited and (b) screamingly misogynistic. Chapter 12, with its portent of doom followed by incongruous and possibly interpolated cheery final verses strike me as rather like the end of The Seafarer.
Next up The Song of Solomon, which is good because I have read it before and it is very short, followed by Isaiah, which I haven’t read and which is very long, though with many famous bits in it.
