Does the Bible mention “back scratching”? No, but the concept of back scratching means, I do for you, and you do for me. Reciprocity. The Bible encourages believers to help one another. It's a metaphor for mutual favors. So, one hand washes the other.

There are some good back scratchers out there. We can assist each other along life’s journey. As back scratchers we bear each other’s burdens. As back scratchers, one is unity and the other is love.  We are back scratchers for the sake of peace and like-mindedness.
