Mattityahu 5:17-19

Orthodox Jewish Bible

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.
