Luk 24:44 And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
Luk 24:45 Then opened he their understanding, that they might understand the scriptures,
2 Tim. 3:16-17 says, "All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; 17 that the man of God may be adequate, equipped for every good work."
The word "inspired" is literally "God-breathed." This is an interesting phrase since it tells us that the Scriptures are from the mouth of God.
