And Abraham would be cut off if he wasn’t circumcised.
God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”
Genesis 17:9, 14 NRSV-CI
Similarly salvation is tied to baptism. You cannot be saved without it.
Jesus answered, “Very truly, I tell you, no one can enter the kingdom of God without being born of water and Spirit."
John 3:5 NRSV-CI
And Paul explicitly links the two.
In him you also were circumcised – not, however, with a circumcision performed by human hands, but by the removal of the fleshly body, that is, through the circumcision done by Christ. Having been buried with him in baptism, you also have been raised with him through your faith in the power of God who raised him from the dead.
Colossians 2:11-12 NET
