"Say to my lord: this is what Puzur-Culgi, the commander of the fortress Igi-hursaja, your servant, says: All the gold and silver that my lord has been fashioning for the gods -- is it not for his own life? For the life of the troops and his land, my king has built the great fortress Igi-hursaja for the people of his land, because of the wicked enemy. [...] May it be known that, by night or by day the enemy's sins are forever grave. I am the loyal servant of my lord Culgi. Let this not be the death of me! May my lord know!"
