'Appear' in the Bible

Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.

What then shall we say to this? If God is on our side, who is there to appear against us?

And again, Isaiah says:The root of Jesse will appear,the One who rises to rule the Gentiles;the Gentiles will hope in Him.
