Might I suggest a book entitled
Commentary on the New Testament Use of the Old Testament
by D. A. Carson, G. K. Beale
It is a scholarly treatment of the origins of OT quotes in the NT. It asserts that about 80% of OT quotes can be traced back to the Septuagint.
80% that seems unrealistic there was about four different versions floating around in that time. OT quotes were probably spoken to the people present, there was different languages with different versions. in the southern parts it was a different culture with their own textbooks like the northern parts. Jesus went with his family to southern judah the temple each year, there is Aramaic language in the New Testament and old Hebrew teachings and all sorts of things as well as different versions quoted from in my opinion.
here’s a site that speaks about the vast difference in and around Judah some places not mentioned is tyre and Sidon full blown Roman provinces.
