Samuel sleeps where the ark lays

Into holy of holies past sheet,
With the bells and the rope for his feet,
If some sin was found inside the priest,
When the music stopped pulled him to meet his grave.
But there's one who had come in a vow,
Served as priest when he was just a kid,
Getting tired,
It's time that he hid,
Went to bed in the room of the presence of God.
Samuel sleeps where the ark lays
