'Keep the Law' in the Bible

Only the LORD give thee wisdom and understanding, and give thee charge concerning Israel, that thou mayest keep the law of the LORD thy God.

They that forsake the law praise the wicked: but such as keep the law contend with them.

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:

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

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