Romans 1:21

1:21 For although they knew God, they did not glorify him as God or give him thanks, but they became futile in their thoughts and their senseless hearts ¹  were darkened.

Romans 1:23

1:23 and exchanged the glory of the immortal God for an image resembling mortal human beings ²  or birds or four-footed animals ³  or reptiles.

¹ tn Grk “heart.”

² tn Grk “exchanged the glory of the incorruptible God in likeness of an image of corruptible man.” Here there is a wordplay on the Greek terms ἄφθαρτος (afqarto", “immortal, imperishable, incorruptible”) and φθαρτός (fqarto", “mortal, corruptible, subject to decay”).

³ sn Possibly an allusion to Ps 106:19-20.
