Mark 1:2
KJV
As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
NIV
as it is written in Isaiah the prophet: “I will send my messenger ahead of you, who will prepare your way”—
Mark quotes two prophets, starting with Malachi 3:1 in Mark 1:2 before proceeding to quote Isaiah 40:3 in Mark 1:3. Modern Bibles suggest that Mark identified Malachi’s writing as Isaiah’s, which is an obvious error.
