Matthew 5:17-19 English Standard Version (ESV)
Christ Came to Fulfill the Law
17 “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. 18 For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. 19 Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven.
Mattityahu 5:17-19 Orthodox Jewish Bible (OJB)
17 Do not think that I came to abolish the Torah or the Neviim. I did not come to abolish but to complete.
18 For, omein, truly I say to you, until Shomayim and haaretz pass away, not one yod, not one tag (ornamental flourish), will pass from the Torah until everything is accomplished.
19 Therefore, whoever annuls one of the least of these mitzvot (divine commandments given by Hashem to Moshe Rebbenu) and so teaches Bnei Adam, shall be called katon (least) in the Malchut HaShomayim; but whoever practices and teaches them, this one will be called gadol (great) in the Malchut HaShomayim.
