Compare Numbers 15:38 and Malachi 4:2 and Matthew 9:20

"... How does one identify allusions, understood as deliberate prompts to readers? The question has been much discussed of late, largely in response to Richard Hays’s work on scripture in Paul. Parallels can be the upshot of unconscious borrowing or coincidence or the common use of stock phrases, and a writer can use biblical language for its own sake, without any desire to recall a particular subtext.

Justin Martyr discovered resemblances between the Pentateuch and Plato and took them to establish the dependence of the latter upon the former; and almost every verse in the New Testament has been thought by someone to depend upon this or that Old Testament text. Theological libraries are full of unsubstantiated intertextual theories, and proposals are often hard to evaluate. John 1:51 (‘you will see heaven opened, and the angels of God ascending and descending upon the Son of man’) obviously has something to do with Jacob’s ladder and Genesis 28:12; but does Mark 10:45 (‘to give his life as a ransom for many’) draw upon Isaiah 53?
