1 Peter 1:10, 18-19

Regarding this salvation, the prophets who prophesied about the grace [of God] that was intended for you, searched carefully and inquired [about this future way of salvation]

For you know that you were not redeemed from your useless [spiritually unproductive] way of life inherited [by tradition] from your forefathers with perishable things like silver and gold, but [you were actually purchased] with precious blood, like that of a [sacrificial] lamb unblemished and spotless, the priceless blood of Christ. [Lev 22:20]
