The M people live in a highland area of Southeast Asia, with fertile rice paddies nestled between mountain ridges. As M farmers harvest the rice, they bind together the heads of grain in small bundles for ease of handling and storage. Each bundle is called a kappa'.
In 1 Corinthians 1:2, Paul called the believers in Corinth "those sanctified in Christ Jesus" (NIV). In the M language, the term for being "in" Christ Jesus is mesa kappa' — "one bundle" with Christ Jesus. This idiom helps the M people understand the vital union that believers have with Christ.
