“O lord, gracious master, who was as a father to me and whom I have requited after the manner of demons, speak to me one word. Declare that you forgive, for the blackness of my sin is ever before me!”

Daniel beckoned him to rise.

“You are forgiven long ago; I have heard of the atonement made by saving Ruth, and by rescuing Isaiah in the riot. You have sinned and have repented. The Lord God requires nothing more.”

“Speed,” interrupted Isaiah, “we must be all haste.”

Then without another word he led the way over the threshold, past the ponderous prison gate, and Darius rejoiced yet again when he found himself beneath the glittering canopy of the stars. No moon. Under the starlight he could see the vague white tracery of the great palace to his left; to his right the outlines of the ziggurats beyond the river, trebly tall in the darkness, and before the temples the opalescent twinkle of some wavelet of the mighty Euphrates, where a constellation was mirrored. Isaiah hastened northward. They saw, far off, a form pacing the embankment above the stream. The starlight touched something that glittered—a soldier’s helmet. Darius heard the chanted call pealing over the sleeping fortress:—

“The Ninib-star[10] rises. Midnight approaches. Marduk prosper Belshazzar our lord!”

“They change sentries soon. Speed!” urged Isaiah. And he led faster along the deserted quay. Soon before them rose a low, square building, and they halted.

“The entrance to the tunnel beneath the river,” whispered Zerubbabel. “Now, if at all, let Jehovah show His mercy. All other exits from the palace fortress are too well watched.”
