The People's Bible Commentary is just what the name implies -- a Bible and commentary for the people.

Although the book of Ecclesiastes is part of the Hebrew Old Testament, its name is actually a Greek word. ... Ecclesiastes means "Teacher," or "Preacher." (Ecclesiastes)

The book's name is taken from the opening verse, "Solomon's Song of Songs." ... also known as Song of Solomon or Canticle, a Latin word meaning song. (Song of Songs)
