'Debtor' in the Bible
people and priest alike, servant and master, female servant and mistress, buyer and seller, lender and borrower, creditor and debtor.
Like a twittering swallow or a crane, so do I chirp and chatter; I moan like a dove. My eyes are weary and dim with looking upward. O Lord, I am oppressed; take my side and be my security [as of a debtor being sent to prison].
