James 2:11

For he that said, Do not commit adultery, said also, Do not kill. Now if thou dost not commit adultery, but killeth, thou art become a transgressor of the law.

This verse is the reason, to be sure, why some insist on construing James' words in this section as a reference to the Law of Moses; but there are some considerations that forbid this. In this verse, James was clearly rebuking those who were dishonoring the poor man, equating their conduct with murder, based upon Jesus' elaboration of that command in Matthew 5:21,22. He even reversed the order of the commandments to achieve more readily this application. Therefore, it is still the Law of Christ which James is holding before his readers. Harper agreed that James here reflects Jesus' explanation of the commandment on killing."[24] Thus, it is no small breach which those who showed the partiality were guilty of. Their unfeeling snobbery toward the poor was exactly the same kind of personality destruction which Jesus equated with murder.
