a Bible passage
28. yea, and things which are not—Yea is not in the Greek. Also some of the oldest manuscripts omit "and." Thus the clause, "things which are not" (are regarded as naught), is in apposition with "foolish … weak … base (that is, lowborn) and despised things." God has chosen all four, though regarded as things that are not, to bring to naught things that are.
