'Whether' in the Bible

Do you not know that when you continually offer yourselves to someone to do his will, you are the slaves of the one whom you obey, either [slaves] of sin, which leads to death, or of obedience, which leads to righteousness (right standing with God)?

If we live, we live for the Lord, and if we die, we die for the Lord. So then, whether we live or die, we are the Lord’s.
