'Imperishable' in the Bible

to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you,

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

but let it be the hidden person of the heart, with the imperishable quality of a gentle and quiet spirit, which is precious in the sight of God.
