Psalms 92:7 - Ellicott's Commentary On The Whole Bible

This verse apparently introduces the statement of the truth which the sensualist does not understand, viz., that the prosperity of the wicked is only momentary, and will render their destruction all the more impressive. The Authorised Version is incorrect in introducing the second conjunction “when.” Literally, In the springing of the wicked like grass, flourish all the workers of iniquity to be destroyed for ever, i.e., the prosperity of an evil class or community gives an impulse to evil, and apparently for a time iniquity seems to have the upper hand, but it is only that the inevitable destruction may be more signal. For the emblematic use of vegetable life in the psalter see Note, Psalms 1:3-4.
