'Whether' in the Bible

(I also baptized the household of Stephanas; besides them, I don't know whether I baptized any other.)

whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come. All are yours,

For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?

For though there are things that are called "gods," whether in the heavens or on earth; as there are many "gods" and many "lords;"

Whether therefore you eat, or drink, or whatever you do, do all to the glory of God.

For in one Spirit we were all baptized into one body, whether Jews or Greeks, whether bond or free; and were all given to drink into one Spirit.

Even things without life, giving a voice, whether pipe or harp, if they didn't give a distinction in the sounds, how would it be known what is piped or harped?

Whether then it is I or they, so we preach, and so you believed.
