Here in the body pent,

Absent from Him I roam,

Yet nightly pitch my moving tent

A day's march nearer home.

James Montgomery (1771-1854): At Home in Heaven.

Modest doubt is call'd

The beacon of the wise, the tent that searches

To the bottom of the worst.

William Shakespeare (1564-1616): Troilus and Cressida. Act ii. Sc. 2.
