Question
Read this sentence from "Excerpt from Young Goodman
Brown."
"Friend," said the other, exchanging his slow
pace for a full stop, "having kept covenant by
meeting thee here, it is my purpose now to
return whence I came."
Now read this dictionary entry for covenant.
covenant (noun) 1. agreement 2. law 3. binding
Answer
The other person in the sentence is referring to an agreement they made to meet, which is a type of covenant, and is now intending to return home, as the covenant has been fulfilled.
