The Eternal Proof: How the Revelation at Mount Sinai Confirms the Torah’s Divine Origin

The ninth principle of Maimonides’ Thirteen Principles of Faith teaches that the Torah we possess today will never be replaced or altered. This article presents the greatest historical proof of the Torah’s eternal truth — its transmission through a national revelation witnessed by millions.

1. The Proof from Mount Sinai — The Eternal Covenant

The purpose of the Revelation at Mount Sinai was to establish an eternal covenant between God and the people of Israel, who together proclaimed: “All that the Lord has spoken, we will do.”
(Shemot 19:8)

At Mount Sinai, the Jewish people were chosen in a public revelation unlike anything else in human history. It was not a private vision to a single prophet — but a collective experience of an entire nation. Approximately three million people witnessed the miracles of the Exodus and heard God’s voice speaking from within the fire on Mount Sinai.

When I ask followers of other religions why they believe their faith is true, given that no mass eyewitness testimony supports it, they usually struggle to answer. Their belief rests on the word of an individual, an act of blind faith — and, as Mishlei (Proverbs) teaches, “A fool believes every word.” (Mishlei 14:15)

When they ask me the same question, my answer is simple: We believe in the Torah not because Moshe alone said he heard God at the burning bush, but because an entire nation heard the voice of God at Mount Sinai.

The Torah itself states this explicitly: “Behold, I come to you in a thick cloud, so that the people may hear when I speak with you, and may also believe in you forever.” (Shemot 19:9)

The Ramban (Nachmanides) comments: “…And they will believe in you forever — in all generations. And if a prophet or dreamer should later arise and contradict your words, they will reject him immediately, for they themselves saw and heard with their own eyes and ears that you reached the highest level of prophecy.”

This, then, is the ultimate proof of the eternal covenant between God and Israel: no other religion ever claimed such a revelation. If God had ever wished to replace His original covenant, He would have had to reveal Himself again before millions of witnesses —
just as He did the first time. A private revelation to one individual could never overturn a public covenant witnessed by an entire nation.

To imagine otherwise would be absurd — like someone trying to cancel a signed contract with witnesses through a messenger, without any legal proof! This, essentially, is the logical flaw behind the claims of Christianity and Islam, which assert that God revoked His covenant with Israel through a solitary “messenger” such as Jesus or Muhammad.

Can any rational person believe that God whispered in one man’s ear that He nullified a covenant made in front of three million people? As Scripture says, “A fool believes every word.”

2. The Torah Itself Declares Sinai the Ultimate Proof

The Torah presents the Revelation at Sinai as the foundation of Israel’s faith and the defining difference between Judaism and all other religions: “For what great nation has a god so near to it as the Lord our God is to us, whenever we call upon Him? Has any people ever heard the voice of God speaking out of the fire, as you have heard, and lived? Or has any god ever attempted to take for himself one nation from the midst of another, with signs and wonders, with a mighty hand and an outstretched arm, and with great terrors — as the Lord your God did for you in Egypt before your eyes? You have been shown to know that the Lord is God — there is none else besides Him.” (Devarim 4:7–35, abridged)

No other faith can produce even the claim of such a mass national revelation. Judaism alone rests on historical eyewitness testimony, not the word of a single individual.

To this day, the Jewish people commemorate these miracles through Passover, Sukkot, and Shavuot, remembering the mighty acts of God witnessed by an entire nation: “Remember the days of old; consider the years of many generations. Ask your father, and he will tell you; your elders, and they will recount it to you.” 
(Devarim 32:7)

The Torah commands us to remember and retell this covenant forever. No other people on earth can claim that their ancestors witnessed open, supernatural events of such magnitude.

No philosophical debate, no reinterpretation of verses can override the testimony of an entire nation that stood before a mountain blazing with fire and heard the voice of God.

3. The Torah Forbids Any Alteration

From this covenant results a binding command that we must never accept any prophet who attempts to change the Torah: “Everything I command you, you shall observe to do; you shall not add to it nor diminish from it. If a prophet or dreamer arises among you and gives you a sign or wonder… saying, ‘Let us follow other gods,’
you shall not listen to that prophet or dreamer. For the Lord your God is testing you, to know whether you love Him with all your heart and soul. You shall walk after the Lord your God, fear Him, keep His commandments, hear His voice, serve Him, and cling to Him.”
(Devarim 13:1–5)

The Torah thus clearly warns that future false prophets will arise and attempt to lead us away from the covenant. Our task is to stand firm and to continue serving God through the commandments given at Sinai. This is the greatest historical proof of Israel’s eternal bond with the Divine.

4. The Supernatural History of the Jewish People

As with Sinai, so with Jewish history: eyewitness reality cannot be denied. For over two thousand years, the Jewish people have lived a history unlike that of any other nation.

Is there any other people who were scattered across the globe, persecuted for millennia, and yet survived with their identity intact,
returning after centuries of exile to their original homeland? Such a story defies natural explanation.

Philosophers and historians have struggled to explain it. How could a small, peace-loving nation outlive the world’s greatest empires — Egypt, Persia, Babylon, Greece, Rome, Christendom, and even Nazi Germany, all of which sought to destroy it? Every empire perished; only Israel endured.

The reasons for antisemitism have shifted, yet the hatred remained constant. And still, the Jewish people survived — without an army, without a homeland, but with an unbroken faith and Torah.

This entire history of exile and survival was foretold in the Torah itself, given over 3,300 years ago. Every prophecy has been fulfilled. History continues to revolve around Israel because God is guiding it toward final redemption.

The Torah even foretold that the Land of Israel would remain desolate in our absence, refusing to flourish under foreign rule: “Your enemies who dwell in it shall be astonished at its desolation.” (Vayikra 26:32)

The Ramban wrote 800 years ago: “Since we left it, no nation or language has been able to make it prosper; all have attempted to settle it, and none have succeeded.”

The supernatural survival of the Jewish people — precisely as predicted in the Torah, stands as a second national testimony, alongside Mount Sinai, to the eternal covenant between God and Israel. From Sinai to today, the evidence is clear: The Torah of Israel is eternal, unbroken, and true.
