NET
12 Those who want to make a good showing in external matters are trying to force you to be circumcised. They do so only to avoid being persecuted for the cross of Christ.
Darby
12 As many as desire to have a fair appearance in [the] flesh, these compel you to be circumcised, only that they may not be persecuted because of the cross of Christ.
KJV
12 As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.
