'Someone' in the Bible

For whenever someone says, “I’m with Paul,” and another, “I’m with Apollos,” are you not unspiritual people?

If any of you has a legal dispute against another, do you dare go to court before the unrighteous, and not before the saints?

But if someone says to you, “This is food offered to an idol,” do not eat it, out of consideration for the one who told you, and for conscience’ sake.

If any person speaks in another language, there should be only two, or at the most three, each in turn, and someone must interpret.

But someone will say, “How are the dead raised? What kind of body will they have when they come?”
