Three trees were planted, oh dear; brother, their branches touched the sky.

This couplet speaks of three trees planted, whose branches reached the sky. It's a beautiful metaphor often used in folk songs to describe something that grows tremendously and has a far-reaching impact. These "three trees" could represent children who grow up to bring pride and joy, or perhaps virtues and good deeds that spread widely and touch many lives. It emphasizes the deep sense of wonder and perhaps the blessing of seeing something nurtured grow beyond expectations, reaching great heights and offering shelter and influence.
