'Law of Moses' in the Bible

If a person is circumcised on a Sabbath day so that the law of Moses can be observed [properly, then why] are you upset with me for restoring a person to complete health on a Sabbath day?

But this crowd, which does not know the law of Moses, [and especially its oral traditions], is cursed [by God]."

Some experts in the law of Moses and Pharisees brought [to Him] a woman who had been caught committing an immoral sexual act and stood her in the middle of the group.

Then the crowd replied to Him, "We have heard from [the writings of] the law of Moses that the Christ will live forever; so how can you say, 'The son of man must be lifted up [i.e., to die]?' Who is this son of man?"
