   The supplied morphology identifies every sampled form as a preposition. In 1 Corinthians 11:8 the APB renders the clause about woman and man as "from" one another; in 1 John 2:19 it renders both departure "out from us" and whether people were "from us"; and in 1 Corinthians 9:14 it renders living "from the gospel." These clauses show the preposition relating an action, person, or thing to its source, point of departure, or group of belonging.
