'Cross' in the Bible

As for me, brothers, if I am still preaching the necessity of circumcision, why am I still being persecuted? In that case the offense of the cross has been removed.

These people who want to impress others by their external appearance are trying to force you to be circumcised, simply to avoid being persecuted for the cross of the Messiah.

But may I never boast about anything except the cross of our Lord Jesus, the Messiah, by which the world has been crucified to me, and I to the world!
