In Luke 11 Jesus tells us what OT is credited as the Word of God. Another reference is made in Luke 24:44
Luke 11:49-51 (with emphases).
“For this reason also** the wisdom of God** said, 'I will send to them prophets and apostles, and some of them they will kill and some they will persecute, so that the blood of all the prophets, shed since the foundation of the world, may be charged against this generation, from the blood of Abel to the blood of Zechariah, who was killed between the altar and the house of God, yes, I tell you, it shall be charged against this generation.”
Jesus says, “from the blood of Abel to the blood of Zechariah.”
Now, there’s a problem with this statement…Zechariah isn’t the last martyr in the OT, if we refer to what both Catholics and Protestants refer to as the OT testament in its current order. Historically Jeremiah is the last martyr in the OT…not Zechariah!
So why would Jesus say from Abel to Zechariah when referring to “the wisdom of God” or the Word of God, OT?
Jesus wasn’t crediting the Septuagint (Greek translation of the OT, which the Catholic and Protestant Bibles are based on) as the written Word of God…what He says as the Wisdom of God. Jesus is referring to the Tanach as the written Word of God in this passage.
