Isaiah 4:4
When—that is, After.
washed— (Zechariah 13:1).
filth—moral (Isaiah 1:21-25).
daughters of Zion—same as in Isaiah 3:16.
purged—purified by judgments; destroying the ungodly, correcting and refining the godly.
blood— (Isaiah 1:15).
spirit—Whatever God does in the universe, He does by His Spirit, "without the hand" of man (Job 34:20; Psalms 104:30). Here He is represented using His power as Judge.
burning— (Matthew 3:11-12). The same Holy Ghost, who sanctifies believers by the fire of affliction (Malachi 3:2-3), dooms unbelievers to the fire of perdition (I Corinthians 3:13-15).
