GAL 2:4

4 [I talked to them privately] because some people [successfully] pretended that they were fellow believers and associated with the true believers. They did that in order that they might observe closely what we do because we are free [from having to obey all the Jewish laws and rituals] because of our close relationship with Christ Jesus [MET]. Those people wanted to make us [like] slaves [MET] [of those rituals by convincing us that we cannot trust Christ solely but that we must also obey all the Jewish rituals].
