In vv. 14-16 man's brief life is brought in, not as a sorrow or as a cloud darkening the sunny joy of the song, but as one reason for the Divine compassion. "He, He knows our frame." The word rendered "frame" is literally "formation" or "fashioning," and comes from the same root as the verb employed in Gen. ii. 7 to describe man's creation, "The Lord God _formed_ man of the dust of the ground." It is also used for the potter's action in moulding earthen vessels (Isa. xxix. 16, etc.). So, in the next clause, "dust" carries on the allusion to Genesis, and the general idea conveyed is that of frailty. Made from dust and fragile as an earthen vessel, man by his weakness appeals to Jehovah's compassion. A blow, delivered with the full force of that almighty hand, would "break him as a potter's vessel is broken." Therefore God handles us tenderly, as mindful of the brittle material with which He has to deal. The familiar figure of fading vegetation, so dear to the psalmists, recurs here; but it is touched with peculiar delicacy, and there is something very sweet and uncomplaining in the singer's tone. The image of the fading flower, burned up by the simoom, and leaving one little spot in the desert robbed of its beauty, veils much of the terror of death, and expresses no shrinking, though great pathos. Ver. 16 may either describe the withering of the flower, or the passing away of frail man. In the former case, the pronouns would be rendered by "it" and "its"; in the latter, by "he," "him," and "his." The latter seems the preferable explanation. Ver. 16_b_ is verbally the same as Job vii. 10. The contemplation of mortality tinges the song with a momentary sadness, which melts into the pensive, yet cheerful, assurance that mortality has an accompanying blessing, in that it makes a plea for pity from a Father's heart.
