He shall shake off his unripe grape as the vine
Either the wicked man himself shall shake off or lose his substance; or God shall shake off from him all that was dear and valuable to him; or he shall be shaken by one providence or another, just as a vine is shaken by a violent wind and tempest, and its unripe grapes are battered off by an hailstorm, or plucked off by the hand, or drop off through rottenness; so it is signified by this metaphor, that a wicked man should be stripped of his wealth and riches in a sudden manner; or his children should be snatched from him in their youth, before they were well grown up to maturity, and so like the unripe grape; perhaps respect is had to Job's case, both with regard to his substance and his family:
and shall cast off his flower, as the olive:
which tree, when shaken in a violent manner, drops its flower, and so brings forth no fruit; it is observed by naturalists F8, that these two trees, the vine and the olive, flourish much about the same time, and suffer much by storms and tempests, which destroy their fruits, and especially when rain falls in the time of their flowering; the some thing is intended in this clause as in the former.
