it comes from the biblical passage psalm 23:4 of the king james translation:
"yea, though I walk through the valley of the shadows, I fear no evil, for I am the destroyer of shadows. yea, knee bent and thine arm folded, He calls upon me: 'kompressor! kompressor! hear my demand!' and so, beckoned he, 'make thy earth formless and thy crop fertile.' He made it so"
