They. — It seems more natural to understand the subject of the verb wandered from the preceding clauses, than to supply a general subject, they; but this is by no means a certain interpretation. It depends on the view we take of the poem. (See Introduction.)
A solitary way. — Better, in a desert track. (Comp. Acts 8:26.) There is a grammatical difficulty, but this does not affect the general intention of the verse. Whether it represents an historical fact, or merely draws an imaginary picture, the reference to the dangers of Eastern travel is equally clear and distinct.
City to dwell in. — Literally, city of habitation, as rendered in Psalms 107:7.
“Boundless and bare
The lone and level sands stretch far away.” — SHELLEY.
