(One verse (Exodus 12:40) states "And the habitation of the children of Israel in the land of Egypt was four hundred and thirty years," and another, (Genesis 15:13) "and they shall serve them and they shall afflict them four hundred years." How are these two verses to be reconciled? Thirty years before the birth of Isaac, the covenant between the pieces (at which the above was said) was made, (and after his birth until the exodus four hundred years elapsed.)
