Charles H. Spurgeon on Psalms 78:8

And might not be as their fathers. The warning is taken from an example at home. He does not say, That they might not be as the nations, which know not God: but, That they might not be as their fathers. Domestic examples of vice are much more pernicious than foreign ones. Hence one says: Sic natura jubet, velocius et citius nos corrumpunt vitiorum exempla domestica. Let us learn from this place, that it is not safe in all things to cleave to the footsteps of our fathers. He speaks of those fathers who perished in the wilderness: of whom, see Numbers 14; Deuteronomy 1, and Ps 68:6. Musculus.
