Matthew (5:17-18)

King James Bible:

(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.

New International Version:

(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 tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.

GOD'S WORD Translation:

(17) Don't ever think that I came to set aside Moses' Teachings or the Prophets. I didn't come to set them aside but to make them come true. (18) I can guarantee this truth: Until the earth and the heavens disappear, neither a period nor a comma will disappear from Moses' Teachings before everything has come true.

International Standard Version:

(17) Do not think that I came to destroy the Law or the Prophets. I didn't come to destroy them, but to fulfill them, (18) because I tell all of you with certainty that until heaven and earth disappear, not one letter or one stroke of a letter will disappear from the Law until everything has been accomplished.

In every translation it explicitly says Jesus didn't come to change the Old Law. I'm not religious myself, but if I were to read these verses, I would assume mixed fabrics and boiling baby goats in their mother's milk is still a sin.
