'Something' in the Bible

For a person is not a Jew who is one outwardly, nor is circumcision something that is outward in the flesh,

For if Abraham was declared righteous by the works of the law, he has something to boast about -- but not before God.

What shall we say then? Is the law sin? Absolutely not! Certainly, I would not have known sin except through the law. For indeed I would not have known what it means to desire something belonging to someone else if the law had not said, "Do not covet."
