'Whether' in the Bible

Do you not know that to whomever you present yourselves [as] slaves for obedience, you are slaves to whomever you obey, whether sin, [leading] to death, or obedience, [leading] to righteousness?

For if we live, we live for the Lord, and if we die, we die for the Lord. Therefore whether we live [or] whether we die, we are the Lord's.
