Isaiah 24:13

When thus it shall be, when this judgment shall be executed, in the midst of the land; in the land. But withal this phrase may intimate that the judgment should not be slight and superficial, and in the skirts of the land; but that it should reach their very heart, their most inward and best defended parts. There shall be as the shaking of an olive tree, & c.; there shall be left a remnant, and that but a very small remnant; as there are some few, and but a few, olives or grapes left after the vintage is over; which, by comparing this with the following verse, seems to be added by way of mitigation, to signify that God would in judgment remember mercy.
