'Whether' in the Bible

Do you not know that if you surrender yourselves as bondservants to obey any one, you become the bondservants of him whom you obey, whether the bondservants of Sin (with death as the result)

trying whether I can succeed in rousing my own countrymen to jealousy and thus save some of them.

Who are you that you should find fault with the servant of another? Whether he stands or falls is a matter which concerns his own master. But stand he will; for the Master can give him power to stand.

If we live, we live to the Lord: if we die, we die to the Lord. So whether we live or die, we belong to the Lord.
