That's Romans 6.
knowing this, that our old man was crucified with
Him, that the body of sin might be [
a]done away with, that we should no longer be slaves of sin. 7 For he who has died has been [
b]freed from sin. 8 Now if
we died with Christ, we believe that we shall also live with Him, 9 knowing that Christ, having been raised from the dead, dies no more. Death no longer has dominion over Him. 10 For
the death that He died, He died to sin once for all; but
the life that He lives, He lives to God. 11 Likewise you also, [
c]reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.
