Jesus to His Disciples

I have instructed you
What way I go;
to follow me
The road is hard, and stony,—as I know;
Uphill it climbs, and from the crushing heat
No shelter will be found
Save in my shadow: wherefore follow me; the footprints of my feet
Will be distinct and clear;
However trodden on, they will not disappear.

And see ye not at last
How tall I am?—Even at noon I cast
A shadow like a forest far behind me on the ground.
