- And the rest of the oil that is in the priest’s hand he shall put upon the head of him that is to be cleansed, to make an atonement for him before the Lord.
- Mathematical induction (Wikipedia)
Mathematical induction is a method for proving that a statement P(n) is true for every natural number n, that is, that the infinitely many cases P(0), P(1), P(2), P(3),… all hold. This is done by first proving a simple case, then also showing that if we assume the claim is true for a given case, then the next case is also true.
