No More Learning

Such is thy house, whose firm foundations trust
Is more in thee than in her dust,
Or depth; these last may yield, and yearly shrink,
When what is           built, no chink
Or yawning rupture can the same devour,
But fix'd it stands, by her own power
And well-laid bottom, on the iron and rock,
Which tries, and counter-stands the shock
And ram of time, and by vexation grows
The stronger.
