John Gill's Exposition of the Whole Bible
Isaiah 24:13
When thus it shall be in the midst of the land among the people,.... When the above judgments shall be executed, the city of Rome shall be destroyed, and the vials of God's wrath are poured but on all the antichristian states, on all the followers of the beast, throughout the whole Romish jurisdiction:
[there shall be] as the shaking of an olive tree, [and] as the gleaning of grapes, when the vintage is done; as when an olive tree is shaken, or beaten with a staff, which was the usual way of gathering olives, and which the word t here signifies, there are some few left upon the uppermost or outermost branches, which cannot be reached; and as, after the vintage is got in, there are some grapes to be gleaned and gathered from the vines; see Isaiah 17:6 so it is here insinuated that there should be some, though but a few, a remnant, according to the election of grace, that should escape the above calamities, and be preserved as a seed for the church of God; and so it will be, that just before the destruction of mystical Babylon, the Lord's people will be called out of her, that they partake not of her sins, and of her plagues, Revelation 18:4. The Targum is,
"for now shall be left alone the righteous in the midst of the earth, among the kingdoms, as the shaking of olives, as the gleaning of grapes after the vintage;''
and to olives and grapes are these gracious persons fitly compared, for the goodness, loveliness, and fruitfulness of them, through the grace of God.
