'Mortal' in the Bible

and exchanged the glory of the immortal God for images resembling mortal man, birds, four-footed animals, and reptiles.

Therefore do not let sin reign in your mortal body, so that you obey its desires.

And if the Spirit of Him who raised Jesus from the dead lives in you, then He who raised Christ from the dead will also bring your mortal bodies to life through His Spirit who lives in you.
