{In Isaiah, the prophet} (en t(9369) Esai(8369) t(9369) proph(8874)(8869)). The
quotation comes from  Mal 3:1  and  Isa 40:3 . The Western and
Neutral classes read Isaiah, the Alexandrian and Syrian, "the
prophets," an evident correction because part of it is from
Malachi. But Isaiah is mentioned as the chief of the prophets. It
was common to combine quotations from the prophets in
_testimonia_ and _catenae_ (chains of quotations). This is Mark's
only prophetic quotation on his own account (Bruce).
