"A well-made wall," said Ulric. "None may break it through. The stones are very large."
Far back from the street were they now, and the house which had appeared small was seen to be of great extent, as if builded down a steep slope. Suddenly the jarl exclaimed:
"A door of a stone! O Jew, how is it that this great marble turneth at thy pushing?"
"See thou," said Ben Ezra. "It is set into the wall upon pivotings. Therefore it is as firm as the rest of the wall unless it shall be tried by one who knoweth the catch-pin at the side. Even then a weak hand moveth it not. I will show thee, and then do thou make trial for thyself."
The jarl watched and understood.
"A marvelous trick!" he exclaimed, opening and shutting the secret door and finding that much strength was required. "O Jew, beyond is a corridor of stone, and I see steps which go downward."
"Before thee is a great deep," replied Ben Ezra. "Thou art trusted as to this thing in the name of Jehovah. Go in, O jarl of the Saxons. Thou wilt go down into the secret chambers of Jerusalem with me."
