Matthew 5:17-19 King James Version (KJV)
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall 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.
