'Burn' in the Bible

as was the custom of the priesthood, he was chosen by lot to enter [the sanctuary of] the temple of the Lord and burn incense [on the altar of incense].

His winnowing fork is in His hand to thoroughly clear His threshing floor, and to gather the wheat (believers) into His barn (kingdom); but He will burn up the chaff (the unrepentant) with unquenchable fire.”
