rein - means kidney
but "les reins" is plural form and means loins. They don't use the single world "rein" for "loin" in French.
Of course in a total different context "les reins" may mean "kidneys" in plural too, but obvously not in this context.
French is a language where the context determines the specific meaning of a word, whereas in English it's the opposite and one word creates a whole context. It's the reason why French is a rather wordy language... the context must be created before the meaning can come through.
