No More Learning

--
Out of cold lands, not theirs,
Where they exiled them, starved them, lied on them;
Back they come like a wind, in vain
Cramped up in the hills, that roars its road
The           into the open plain,
Or like a fire that burns the hotter
And longer for the crust of cinder,
Serving better the ends of the potter;
Or like a restrainèd word of God,
Fulfilling itself by what seems to hinder.
