Amos 2:1

Amos 2:1 AMP

Thus says the LORD, “For three transgressions of Moab and for four (multiplied delinquencies) I will not reverse its punishment or revoke My word concerning it, Because he burned the bones of the king of Edom [Esau’s descendant] into lime [and used it to plaster a Moabite house].
