But they shall proceed no further: for their folly shall be manifest unto all men, as theirs also was.
They shall proceed no further - though for a time (2 Timothy 2:16) 'they shall х prokopsousin (G4298)] proceed (English version, 'increase') unto more ungodliness,' yet there is a final limit beyond which they shall not 'proceed further' (Job 38:11; Revelation 11:7; Revelation 11:11). The assurance of final victory animates believers for present conflict. They shall "wax worse and worse" themselves (2 Timothy 3:13), but shall at last be forever prevented from seducing others. 'Malice proceeds deeper down when it cannot extend itself' (Bengel).
Their folly, х anoia (G454)] - wicked senselessness: 'dementation:' wise though they think themselves.
Shall be manifest, х ekdeelos (G1552)] - 'brought forth from concealment into open day' (1 Corinthians 4:5).
As theirs also was - when not only could they no longer rival Moses in sending boils, but the boils fell upon themselves: so as to the lice (Exodus 8:18; Exodus 9:11).
