Mat 5:18 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.
Since truly I am telling you all until possibly it shall pass away the sky and the earth. An "i", one, or one tittle never shall pass away from the law it might all come into being.
This verse has a lot of strange things going on with singular verbs and plural subjects. They are covered up completely by KJV translation, but they can be explained by working through the Greek carefully. Also, the word translated as "fulfilled" is not the Greek word usually translated as "fulfilled", the word we saw in the previous verse, Mat 5:17 .
The "verily" phrase that begins this quote is used frequently by Christ as a personal signature. Its vocabulary and meaning is discussed in detail in this article. Christ makes fun of his frequent use of it.
The Greek word for "for" is used to indicate that the phrase offers and explanation.
The word translated is as "verily" is an exclamation that means "truly" or "of a truth", but it is not an adjective or an adverb but an exclamation. It is an untranslated Aramaic word that is echoed by a similar Greek word, and a good piece of evidence that Christ taught in Greek, not Aramaic.
The word translated as "say" is the word for "speak" or "say that Christ uses to refer to his own teaching and its content. It is one of several words translated as "see", "say", or "tell".
The word translated as "till" means "until" or "while".
Next is a Greek particle that the verb might possibly happen, even that is likely to happen, but that the speaker is not certain that it will happen.
The word translated as "heaven" means sky, the climate, and the universe. It also meant the home of the gods in a physical sense: the sun, moon, and planets were named for the gods. More about the word in this article. It is singular here. The phrase here includes the article "the" which is left out of the KJV, so "the sky". When Christ talks about, for example, "the Father in heaven" it is always plural, literally "the skies". So this is more limited, possibly referring to the planet's sky rather than all of the universe.
The "pass away" verb means literally "start beyond" and can mean "go by." "pass by," or "pass away." It is not in the future tense, but a form indicating something that might happen at some point in time. The verb is singular though there are two words following it, both in the form of a subject. One explanation for this is that the two together are considered a single unit. Another possible explanation is that in speaking this, Christ as thinking about "the sky" and added "and the earth". More about Christ's use of the terms "heaven and earth" see this article.
"Jot" is from the Greek word for the letter iota, which is our letter "i". The word for "one" follows this word.
"Tittle" is from the Greek form of the apostrophe. The word "one" precedes this word, but the form doesn't match.
The phrase "in no wise" comes from the use of the two forms of negative in Greek, ou and me. The first is the objective negative, the negative of fact, while the second is the subjective negative, the negative of opinion. Christ uses them together for a sense of impossibility. "Never" is the simplest form to translated this.
The second "pass away" is also single, again, despite this time being preceded by the multiple subjects. The fact that the subject preceded the verb make it more difficult to argue that this verb form is an afterthought. However, it is also more difficult to think of the "iota, one, and one apostrophe" as a unit, especially since the "one apostrophe" do not agree in form. Perhaps this was spoken as a question with what follows as an answer.
The Greek word translated as "law" describes the social norms, which can be from "tradition", "common practice," or the "laws." Christ also uses it to refer to the first five books of the OT written by Moses. Because the references are to writing, we can assume Christ is referring to the written law.
The "till" is the same word that started this verse.
The word translated as "all" is the Greek adjective meaning "all", "the whole", "every," and similar ideas. While technically, this is an adjective, it is often used as a pronoun or a noun. Again, we have a problem with the form matches that of "the law" but as an object here, that is, what the law becomes "it become all". However, it could also be the subject of the sentence as the neutral "everything", "everything comes into being".
The Greek verb translated as "is fulfilled" is not the Greek word translated in Mat 5:17 as "fulfill", which is the word that the NT typically uses as "fulfilled". It is a very different and very common Greek word meaning "to become," that is, "to come into being." It is in the subjunctive voice indicating uncertainty. It is also in a form referring to a subject acting on itself. However, this is also in the aorist tense, indicating something that happens at a point in time. It is in the singular. However, if we assume the "all" above is neutral, that is, no referring to "the law", it still works even though "all" is plural because neutral plural verbs are considered collectives and therefore can be used with singular verbs.
The Spoken Version:
“this is why I tell you true,” he said, using an expression that would become one of his catchphrases, “while possibly it just might pass away.”
He paused as if thinking and someone called out, “The law?” This echoed what everyone was thinking.
He smiled and shook his head, “no”, and pointed up, and said, “The sky.” Then he pointed down and added, “Also the ground.”
Many laughed, some perhaps at the idea of the whole universe being destroyed.
“An “i”, one, or apostrophe, one?” he asked mysteriously, writing them in the air with his hands, “Never it is going to pass out of the law, while...”
He paused. The crowd waited, not knowing what to expect.
“Until everything might,” he said emphasizing the possibility’, “bring itself into existence.”
