'Someone' in the Bible

For who regards you as superior or what sets you apart as special? What do you have that you did not receive [from another]? And if in fact you received it [from God or someone else], why do you boast as if you had not received it [but had gained it by yourself]?

For if someone sees you, a person having knowledge, eating in an idol’s temple, then if he is weak, will he not be encouraged to eat things sacrificed to idols [and violate his own convictions]?

But if anyone says to you, “This meat has been offered in sacrifice to an idol,” do not eat it, out of consideration for the one who told you, and for conscience’s sake—

But someone will say, “How are the dead raised? And with what kind of body will they come?”
