When Hadrian issued his terrible decrees outlawing the practice of Judaism, and in particular making it illegal to teach Torah on the pain of death, it was Rabbi Akiva who boldly stood up in a public square and began teaching Torah. The Romans, indeed, arrested him and put him in prison. In the same prison was his friend Pappus, who was caught for selling goods on the black market. “Happy are you, Rabbi Akiva,” Pappus told him, “that you were arrested for teaching Torah. Woe to Pappus, who was arrested for trying to make a few dollars.”
Rabbi Akiva was executed by the Romans on the eve of Yom Kippur in the city of Caesarea where even today one can see the ruins of Hippodrome, which was the arena where the Romans executed people publicly. Even as they tortured him to death he recited the final words of a Jew, the great proclamation of faith in God and His oneness, “Hear, O Israel, God is our God; God is one.”
His students, who stood nearby as the Romans were flaying flesh with iron combs, asked, “Even till now?” Are you still thinking about your obligations to God even at this horrific, tragic moment?
“All my life,” he said to them, “I waited for the opportunity to show how much I love God, and now that I have the opportunity should I waste it?”
Then, “he died with the word One” on his lips, the Talmud (Berachos 61b) says.
