Thou shalt come to thy grave in full age - That is, thou shalt have long life; thou shalt not be cut down prematurely, nor by any sudden calamity. It is to be remembered that long life was regarded as an eminent blessing in ancient times; see the notes at Isaiah 65:22.
Like as a shock of corn cometh in in his season - Margin, “ascendeth.” As a sheaf of grain is harvested when it is fully ripe. This is a beautiful comparison, and the meaning is obvious. He would not be cut off before his plans were fully matured; before the fruits of righteousness had ripened in his life. He would be taken away when he was ripe for heaven - as the yellow grain is for the harvest. Grain is not cut down when it is green; and the meaning of Eliphaz is, that it is as desirable that man should live to a good old age before he is gathered to his fathers, as it is that grain should be suffered to stand until it is fully ripe.
