“Do not think…” v.17

Two Major Components of the Old Testament:

Law—“Torah”
Prophecy

“To fulfill…”— plerosai (aorist, active, infinitive) - because of the disjunction (“or”) between “law” and “prophets,” it implies that this phrase has a double meaning. He fulfills the law in one way, and the prophets in another way.

Jesus’ Fulfillment…

Fulfillment of the Law
ulfillment of Prophecy

“Till all is fulfilled” v.18—

"Jot" – Yod — The "y" sound in Hebrew – the smallest letter in the Hebrew Alphabet. Basically, it's the equivalent of the English apostrophe: '

“Tittle” – (Greek keraia) — this is the smallest distinguishing mark in Hebrew letters, similar to the mark at the bottom of the letter "Q." In Hebrew, that mark is the difference between the equivalent R and D sounding letters in Hebrew. This mark is small but still very significant. In Deuteronomy 6:4, this mark distinguishing these two letters is the difference between the verse saying "The Lord our God, the Lord is one," and "The Lord our God, the Lord is another." Those are very different messages, so this tiny mark is critical to the preservation of the truth.

“These commandments” v.19, 20 —
