Deuteronomy 4:16
14 Moreover, at that same time the Lord commanded me to teach you statutes and ordinances for you to keep in the land that you are about to enter and possess. 15 Be very careful, then, because you saw no form at the time the Lord spoke to you at Horeb from the middle of the fire. 16 I say this so you will not corrupt yourselves by making an image in the form of any kind of figure. This includes the likeness of a human male or female, 17 any kind of land animal, any bird that flies in the sky, 18 anything that crawls on the ground, or any fish in the deep waters under the earth.
Romans 1:23
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 were darkened. 22 Although they claimed to be wise, they became fools 23 and exchanged the glory of the immortal God for an image resembling mortal human beings or birds or four-footed animals or reptiles. 24 Therefore God gave them over in the desires of their hearts to impurity, to dishonor their bodies among themselves.
Notes and References
"... Paul does mention the “reptile” elsewhere in the brief creature list associated with idolatry in Romans 1:23 (compare 1 Corinthians 8–11:1): “. . . they exchanged the glory of the immortal God for images (εἰκών) in the likeness (ὁμοιώματι) of mortal man and birds and animals and creeping things (ἑρπετῶν).” While here alluding to Psalm 106:20, Paul also echoes Deuteronomy 4:15–19, with “image” and “likeness” occurring in parallel, along with the terrestrial creatures listed there. Fitzmyer suggests this likely accounts for Paul’s awkward syntax there. See Joseph A. Fitzmyer, Romans, AB 33 (New York: Double Day, 1993), 283 ... With Deuteronomy 4:15–19 as an essential part of the background of Romans 1:23, crucial neglected connections can be made with the language of 1 Corinthians 15:39–49 ..."
