However, Wisdom 2:12-20 was not written originally as a prophecy. The same themes can apply to faithful Christians today. This contrasts with a text like Isaiah 53 that sets up the enigmatic Servant that suffers on behalf of His people. Wisdom 2 is talking about a "righteous man", not Christ Himself. To take similarities and claim prophecy in this case is pure eisegesis.
Even if Wisdom 2:12-20 was intended to speak of the coming Messiah, it does not require us to accept it as inspired or canonical. The statements could be gleaned from what the canonical books of the Old Testament teach. In fact, the Roman Catholic New American Bible Revised Edition has this footnote:
The authorship of the Book of Wisdom is unknown. It was not a part of the Jewish canon. It was originally composed in Greek. It was written during a time when there were no prophets alive in Israel. The author was obviously familiar with texts of the Old Testament, but that factor does not in itself prove the work to be inspired. The authors of the New Testament never cited Wisdom 2:12-20, which would be ironic if it truly was a Messianic prophecy.
