The flame consumeth the chaff. Literally, “as dry grass designed for the flame sinks down.” Dead Sea scroll 1QIs (see Vol. I, p. 31; Vol. IV, p. 86) reads, “as a flaming fire he sinks down.” The latter resembles the reading of the LXX, “burned together by an unrestrained fire.”
As rottenness. These men are utterly corrupt, and they will perish in their own corruption. As quickly as dry grass catches fire and is reduced to ashes, so will they be consumed.
The law of the Lord. Terrible are the results when the law of the Lord is rejected (see GC 586), for without it there is no way of determining what is good and what is evil. It was because these men had cast aside God’s law that they sank so low in iniquity as to engage in the practices described in vs. 8-23.
Despised the word. God’s word is always true and just. But these men despised His holy word (see on v. 21), and when men take this attitude there is little hope for them.
