'Hot' in the Bible

“Heap on wood, kindle the fire,Boil the meat well [done]And mix in the spices,And let the bones be burned.

“Then set the empty pot (Jerusalem) back on the coalsSo that it may be hotAnd its bronze may glowAnd its filthiness may be meltedAnd its rust (scum) may be consumed.

therefore thus says the Lord God, “Most certainly in the fire of My jealousy (love for that which is Mine) I have spoken against the rest of the nations and against all Edom, who appropriated My land for themselves as a possession with wholehearted joy and with uttermost contempt, so that they might empty it out [and possess it] as prey.”
