Galatians 5:2 KJV
Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
Galatians 5:6 KJV
For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Galatians 5:11 KJV
And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
