ISB ~ Romans 16 v20

crush Satan under your feet:Paul desires the Roman Christians to understand the true difference between “good” and “evil” (16:19) and so share in Christ’s victory over the devil (1 Jn 3:8).

• Paul is alluding to the first biblical prophecy, Gen 3:15, which promises that a Redeemer will trample the satanic serpent underfoot. Paul extends this prophecy about the Messiah to the entire messianic people.
