18 For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors,

Read 1 Peter 1:18 Using Other Translations

Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold,
For you know that God paid a ransom to save you from the empty life you inherited from your ancestors. And it was not paid with mere gold or silver, which lose their value.
