I will turn your feasts into mourning, And all your songs into lamentation; And I will make you wear sackcloth on all your bodies, And baldness on every head. I will make it like the mourning for an only son, And the end of it like a bitter day.
And the end thereof as a bitter day - Most griefs have a rest or pause, or wear themselves out. “The end” of this should be like the beginning, nay, one concentrated grief, a whole day of bitter grief summed up in its close. It was to be no passing trouble, but one which should end in bitterness, an unending sorrow and destruction; image of the undying death in hell.
