A second second trial was that the deceased would have to recite a negative confession "when [she or] he descends to the hall of the Two Truths." In the statement, he or she swore that they had not engaged in specific behaviors while alive. According to Egyptologist Ahmed Osman, one translation of the statement reads:
"Hail to thee, great God, Lord of the Two Truths. I have come unto thee, my Lord, that thou mayest bring me to see thy beauty. I know thee, I know thy name, I know the names of the 42 Gods who are with thee in this broad hall of the Two Truths . . . Behold, I am come unto thee. I have brought thee truth; I have done away with sin for thee. I have not sinned against anyone. I have not mistreated people. I have not done evil instead of righteousness . . .
I have not reviled the God.
I have not laid violent hands on an orphan.
I have not done what the God abominates . . .
I have not killed; I have not turned anyone over to a killer.
I have not caused anyone's suffering . . .
I have not copulated (illicitly); I have not been unchaste.
I have not increased nor diminished the measure, I have not diminished the palm; I have not encroached upon the fields.
I have not added to the balance weights; I have not tempered with the plumb bob of the balance.
I have not taken milk from a child's mouth; I have not driven small cattle from their herbage...
I have not stopped (the flow of) water in its seasons; I have not built a dam against flowing water.
I have not quenched a fire in its time . . .
I have not kept cattle away from the God's property.
I have not blocked the God at his processions. 5

Not exactly the 10C, but some definite similarities. Odd they had a commandment against building dams, though.
The Egyptians lived and died by the annual flooding of the Nile. Anyone who impeded the flood (which fertilized the soil along the river) was probably considered as evil as a murderer, in Egyptian eyes.
