Son of Man : Come in under the shadow (19-26)

19             What are the roots that clutch, what branches grow
20             Out of this stony rubbish? Son of man,
21             You cannot say, or guess, for you know only
22             A heap of broken images, where the sun beats,
23             And the dead tree gives no shelter, the cricket no relief,
24             And the dry stone no sound of water. Only
25             There is shadow under this red rock,
26             (Come in under the shadow of this red rock),
