A.T. Robertson Commentary Matthew 12:17

"that it might be fulfilled which was spoken through Isaiah the prophet, saying," — Matthew 12:17 (ASV)

That it might be fulfilled (ινα πληρωθη). The final use of ινα and the sub-final just before (verse 16). The passage quoted is Isa 42:1-4 "a very free reproduction of the Hebrew with occasional side glances at the Septuagint" (Bruce), possibly from an Aramaic collection of Testimonia (McNeile). Matthew applies the prophecy about Cyrus to Christ.
