1 Chronicles 20
In English (especially colloquial English), we have two sets of famous Rs. More specifically, the three Rs. There is one set of Rs to describe the main subjects in school: reading, writing, and ‘rithmetic (math). Of course, these three words don’t all begin with the letter r, but all of them begin with the sound of the letter r. More recently, a second pair of three Rs has been coined and made famous by the environmental movement, as a reminder for what we should do to protect the Earth: reduce, reuse, recycle.
