Jesus actually said this too:

"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. For 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. So 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."
