What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, "You shall not covet."
NIV
What then do we conclude? Is the Law identical with sin? Certainly not! Nevertheless, if it had not been for the Law, I should not have recognized sin or have known its meaning. [For instance] I would not have known about covetousness [would have had no consciousness of sin or sense of guilt] if the Law had not [repeatedly] said, You shall not covet and have an evil desire [for one thing and another]. [Exod. 20:17; Deut. 5:21.]AMP
What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
KJV
Resist him, standing firm in the faith, because you know that your fellow believers throughout the world are undergoing the same kind of sufferings.
NIV
Withstand him; be firm in faith [against his onset--rooted, established, strong, immovable, and determined], knowing that the same (identical) sufferings are appointed to your brotherhood (the whole body of Christians) throughout the world.
AMP
Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
