The Hebrew word so rendered means “boiling” or “effervescing.” From Isa. 33:12 it appears that lime was made in a kiln lighted by thorn-bushes. In Amos 2:1 it is recorded that the king of Moab “burned the bones of the king of Edom into lime.” The same Hebrew word is used in Deut. 27:2-4, and is there rendered “plaster.” Limestone is the chief constituent of the mountains of Syria.

the substance obtained form limestone, shells, etc., by heat. It is noticed only three times in the Bible, viz., in (27:2) (Authorized Version “plaster”), (Isaiah 33:12) and Amos 2:1
