Amos 2:1
Thus saith the LORD; For three transgressions of Moab, and for four, I will not turn away the punishment thereof; because he burned the bones of the king of Edom into lime: Thus saith the LORD; For three transgressions of Moab, and for four, I will not turn away the punishment thereof; because he burned the bones of the king of Edom into lime:
Moab stands condemned for burning the bones of the king of Edom into lime. That burning was counted as a transgression, and for it punishment would not be turned away but would fall upon Moab. The act was a desecration of the dead.
