Whilst it [is] yet in its greenness
Before it is come to its full height, or to a proper ripeness; when as yet it has not flowered, or is about it; before the time usual for it to turn and change; it being without moisture, water, or watery clay, will change;
[and] not cut down;
by the scythe, or cropped by the hand of man,
it withereth before any [other] herb;
of itself; rather sooner than such that do not require so much moisture; or in the sight and presence of them, they looking on as it were, and deriding it; a poetical representation, as Schultens observes: next follows the accommodation of these similes to wicked and hypocritical men.
