'Keep the Law' in the Bible

Well, if a male child undergoes circumcision on the Sabbath, to keep the law of Moses from being broken, are you angry with me for making a man perfectly well on the Sabbath?

But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.

Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:

Go with these, and make yourself clean with them, and make the necessary payments for them, so that they may be free from their oath: and everyone will see that the statements made about you are not true, but that you put yourself under rule, and keep the law.

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.

Then he who is physically uncircumcised but keeps [the spirit of] the Law will judge you who, even though you have the written code and circumcision, break the Law.

Take on yourselves one another's troubles, and so keep the law of Christ.

For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.
