Jeremiah 4:4

4:4 Just as ritual circumcision cuts away the foreskin

as an external symbol of dedicated covenant commitment,

you must genuinely dedicate yourselves to the Lord

and get rid of everything that hinders your commitment to me,

people of Judah and inhabitants of Jerusalem.

If you do not, my anger will blaze up like a flaming fire against you

that no one will be able to extinguish.

That will happen because of the evil you have done.”

so that you may yet be delivered.

Colossians 2:11

2:11 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.
