'Mortal' in the Bible

and exchanged the glory and majesty and excellence of the immortal God for an image [worthless idols] in the shape of mortal man and birds and four-footed animals and reptiles.

Therefore do not let sin reign in your mortal body so that you obey its lusts and passions.

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