Luke 3:17
His winnowing fork is in his hand to clear his threshing floor and to gather the wheat into his barn, but he will burn up the chaff with unquenchable fire — the threshing-floor image is the agricultural picture of final judgment: grain and chaff separated by the fork, the wheat gathered and the chaff burned. The two outcomes communicate that the coming one arrives not only to save but to judge — the same event produces both results depending on what one is.
