He; either,
1. The wicked man, who by his sins is the author of his own ruin. Or,
2. God, who is easily understood, both from the matter and context. Shall shake off, Heb. shall take away by violence. His unripe grape, i. e. his fruit, his children, or other comforts, before their time. As the vine, i.e. as the vine either itself droppeth, or rather loseth, its tender grapes, which are plucked off by a violent hand. As the olive; which flourisheth much about the same time with the vine, and is commonly handled in the same manner.
