I love how the author has really taken this verse and allowed us to see the Hebraic thought behind what Yeshua is saying. If you don’t understand the culture of the time the Scriptures are written you simply cannot appreciate what is being said in Matthew 5:17-18
Think not that I am come to destroy the Law, or
the prophets: I am not come to destroy, but to fulfill. For verily, I say unto you, Till heaven and earth pass, not one jot or one tittle shall pass from the Law, till all be fulfilled.
For the modern-day Christians the previous verse means that the Torah and the others books of the “Old Testament” have been fulfilled, or done away with. They say that, “all was fulfilled” when Yahshua said, “it is finished” and the Law is no longer relevant. Such a belief about the Torah could not be farther from the truth. Just consider the Master’s own words. Has heaven and earth passed away? Of course not! Then, the Torah and the prophets remain necessary and essential to living the Almighty’s will.
Yahshua quoted a Hebrew idiom when He said He came not to destroy the Law or the prophets. He was using a familiar phrase easily understood during Biblical times. If someone heard a Torah teaching and didn’t agree, they would say that the Teacher was “destroying the law.” If they heard a heard a teaching they thought was the right interpretation they would then say, “yes, this is fulfilling the law.” Yahshua had been accused of misinterpreting the Torah, yet He said that He was actually rightly and correctly teaching it. Traditional Jewish writings support this idiom, “Should all the nations of the world unite to uproot one word of the Law, they would be unable to do it,” Leviticus Rabbah 19:2. To understand the meaning of this verse, everything hinges on the meaning of the words “destroy” and “fulfill” in verse 17. What does Yeshua mean by “destroy the Law” and “fulfill the Law”? “Destroy” and “fulfill” are technical terms used in rabbinic argumentation. When a sage felt that a colleague had misinterpreted a passage of Scripture, he would say, “You are destroying the Law!” Needless to say, in most cases, his colleagues strongly disagreed. What was “destroying the Law” for one sage was “fulfilling the Law” (correctly interpreting Scripture) for another,” wrote Bivin and Bizzard in their book Understanding the Difficult Words of Yahshua.
In plain English, Yahshua is saying, “Never imagine for a moment that I intend to abrogate the Law by misinterpreting it. My intent is not to weaken or negate the Law, but by properly interpreting Elohim’s written Word, I aim to establish it, that is, make it even more lasting. I would never invalidate the Law by effectively removing something from it through misinterpretation. Heaven and earth would sooner disappear than something from the Law. Not the smallest letter in the alphabet, the jot or yod, nor even its decorative spur, the tittle, will ever disappear from the Law,” wrote Bivin and Blizzard on page 155.
