'Perishable' in the Bible

so that the proof of your faith, being more precious than gold which is perishable, even though tested by fire, may be found to result in praise and glory and honor at the revelation of Jesus Christ;

knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers,

for you have been born again not of seed which is perishable but imperishable, that is, through the living and enduring word of God.
