Baptism and circumcision

What is the difference between Circumcision in the OT and Baptism in the NT?

Circumcision (involving males) is no longer commanded by God (1 Corinthians 7:19; Galatians 5:1-6; 6:15). God commands that all people—male and female—be baptized (Matthew 28:19-20).

Colossians 2:11-12 speaks of a parallel between circumcision and Baptism, and the blessings that Baptism bestows: “In him you were also circumcised with a circumcision not performed by human hands. Your whole self ruled by the flesh was put off when you were circumcised by Christ, having been buried with him in baptism, in which you were also raised with him through your faith in the working of God, who raised him from the dead.”
