^1 1-3 How wonderful, how beautiful,
    when brothers and sisters get along!
It's like costly anointing oil
    flowing down head and beard,
Flowing down Aaron's beard,
    flowing down the collar of his priestly robes.
It's like the dew on Mount Hermon
    flowing down the slopes of Zion.
Yes, that's where God commands the blessing,
    ordains eternal life.
