A pious man was walking along the sea-shore near Haifa when doubt crept into his mind. He had heard the sages' teaching that the gates of the future Jerusalem would be made from single pearls — each pearl carved into a gate thirty cubits high and thirty cubits wide. And he could not believe it.
"How is this possible?" he muttered to himself. "A pearl the size of a dove's egg is a rarity. A pearl large enough to make a gate? The sages must be speaking in metaphor. Surely they cannot mean this literally."
As the words formed in his mind, a voice descended from heaven — a bat kol, a divine echo. "You dare to doubt the words of the sages?" the voice thundered. The pious man fell to his knees, terrified. He had questioned a teaching that carried the authority of tradition, and heaven had heard him.
"I repent!" the man cried out. "I should not have doubted. I accept the teaching of the sages as truth." His repentance was immediate and sincere — not the gradual turning of a lukewarm heart, but the instant, wholehearted teshuvah (repentance) of a man who realizes he has crossed a line.
And because he repented so swiftly, God granted him a vision. The sea before him parted — not as it had parted for Moses, but just enough to reveal what lay beneath. At the bottom of the sea, the pious man saw angels laboring — sawing, cutting, polishing enormous pearls into the exact dimensions the sages had described. Thirty cubits by thirty cubits. Real pearls. Real gates. Being prepared right now, at the bottom of the ocean.
The man rose from his knees, trembling but transformed. He never doubted the sages again. What the eye cannot see, the heart must trust — and sometimes, for those who repent quickly enough, the eye is granted a glimpse of what was always there.
