Do not think that I have come to abolish the Law or the Prophets. I have not come to abolish them, but to fulfill them.
Jesus says he has come to fulfill the Law and the Prophets, not abolish them.
The verse states his relation to Scripture.
17Do not think that I have come to abolish the Law or the Prophets. I have not come to abolish them, but to fulfill them. 18For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished. 19So then, whoever breaks one of the least of these commandments and teaches others to do likewise will be called least in the kingdom of heaven; but whoever practices and teaches them will be called great in the kingdom of heaven. 20For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
