'Lime' in the Bible

“The peoples will be burned to lime,Like thorns cut down which are burned in the fire.

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].
