Paul quotes Luke 10:7 as scripture in 1 Tim 5:18 For the Scripture says, “You shall not muzzle an ox when it treads out the grain,” and, “The laborer deserves his wages.”  He quotes an Old Testament Verse and a New Testament verse and calls them both scripture.

1 Thes 4:15 “For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep.”

Gal 1:12 “For I did not receive it from any man, nor was I taught it, but I received it through a revelation of Jesus Christ.”

1 Cor 14:37  “If anyone thinks that he is a prophet, or spiritual, he should acknowledge that the things I am writing to you are a command of the Lord.”

John 14:26 “But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.”
