DEUTEROCANONICAL BOOKS IN THE NEW TESTAMENT
Of the approximately 300 Old Testament quotes in the New Testament, approximately 2/3 of them came from the Septuagint (the Greek translation of the Old Testament) which included the deuterocanonical books that the Protestants later removed.
This is additional evidence that Jesus and the apostles viewed the deuterocanonical books as part of canon of the Old Testament.
Go here for examples:
The Protestants attempt to defend their rejection of the deuterocanonicals on the ground that the early Jews rejected them.
However, the Jewish councils that rejected them (e.g., School of Javneh (also called “Jamnia” in 90 - 100 A.D.) were the same councils that rejected the entire New Testatment canon.
Thus, Protestants who reject the Catholic Bible are following a Jewish council that rejected Christ and the Revelation of the New Testament.
