And the LORD your God will put out those nations before you by little and little: you may not consume them at once…
In listening to the sound by which a clock or watch marks the passing of the diminutive portions of time, one might almost fancy that deductions so extremely small would never wear away the whole duration of a long life. But it has been by such minute lapses in never ceasing succession that the vast series of ages since the creation has passed away; it has been by this succession of instants that all our ancestors have completed their sojourn on earth, and by this it will be that we shall one day have arrived at the end of our mortal existence. Each passing moment, then, may be regarded as having a relation to the end, and everything which hints to us that moments are passing, may be a monition to us to be habitually at the great work which ought to be accomplished against the period when the last of them shall come.
