Brethren in Christ, God give you Peace.
Thanks for all the wonderful discussion! Someone had asked earlier if this had something to do with the Apocrypha. It does not. I personally spend much time meditating on the life of Jesus, in order that by coming to know Him better, I might be better able to imitate Him. This thought came up in one of my meditations and I wanted to explore it with you at CF so that you too may join me in getting to know our Lord and His Word better. Had it been my intention to make some point about the Apocrypha, I would have posed a different question/thought.
As it is, the answer(s) to this question, in my opinion, has negative implications for those believing in sola Scriptura (non-Catholics) AND for those believing (Catholics) that the Septuagint (as we now have it in the Catholic Bible) was the Scripture used by Jesus, His apostles and disciples and everywhere else in the region (Gentiles, Sadduccees and Samaritans excepted, of course). But I am not interested in discussing how either of those implications affects those various arguments. I am interested in getting more familiar with the Word of God. If anyone wants to explore those implications, please dont do it here.
Here are the verses so far offered in response to the OP: Mt 2:23; Mt 27:9-10; Jn 18:9 and; Lk 1:68-70.
Mt 2:23 is clearly not in Scripture. What Matthew is referring to, we will not know until we join him.
Mt:27:9-10 is not in Jeremiah directly, though it is written as a quote from Jeremiah. It has some similarities with Jeremiah 18: 2-3 and Jeremiah 32: 6-15. Part of it is also found in Zechariah 11:12-13. I think it is safe to say on this one that it, like Mt 2:23, is something outside of our known Scripture.
Jn 18:9 is related to Jesus prayer in Jn 17:12. It doesnt claim to come from the OT.
Lk 1:68-70 is a new prophesy by Zechariah, the father of John the Baptist. While it has parts that are drawn from Scripture, because it is said to be Zechariahs prophesy, it also doesnt claim to come from the OT.
So far, I think that we have found two that fit the OP.
Consider too Jn 5:46-47. Does anyone know what specific writing of Moses Jesus is talking about? I can almost see the Pharisees that He was speaking too collaborating and pouring through Scripture all night after Jesus told them this, trying to figure out what He was talking about! You can bet they did just that!
God Bless,
