'Imperishable' in the Bible

Now everyone who competes exercises self-control in everything. However, they do it to receive a crown that will fade away, but we a crown that will never fade away.

and into an inheritance that is imperishable, uncorrupted, and unfading, kept in heaven for you.

since you have been born again—not of perishable seed but of imperishable—through the living and enduring word of God.

Instead, it should consist of what is inside the heart with the imperishable quality of a gentle and quiet spirit, which is very valuable in God’s eyes.
