The prophet sees the devastation left and compares it to the fields after the harvest when there is only enough for the poor to find. But there has NOT been a harvest, not enough even for the poor.
In the city desolation is left,
And the gate is stricken with destruction.
When it shall be thus in the midst of the land among the people,
It shall be like the shaking of an olive tree,
Like the gleaning of grapes when the vintage is done.
PRAY FOR A SPIRITUAL HUNGER TO OVERTAKE ISRAEL.
