I know "karma is a b**ch", "what goes around, comes around", and "you reap what you sow", but I'm looking for a much more elaborate phrase that's very descriptive, which I had heard ages ago but can't recall it anymore.
What goes around comes around idiom
used to say that if someone treats other people badly he or she will eventually be treated badly by someone else. (M-W)
I'm looking for a much more elaborate phrase that's very descriptive.
I suspect you're looking for this:
As you sow so shall you reap.
From The Phrase Finder:
Your deeds, good or bad, will repay you in kind...
From the Bible, Galatians VI (King James Version):
Whatsoever a man soweth, that shall he also reap.
Got what I was looking for!
"Turnabout is fair play".
