'Someone' in the Bible

Who ever goes to war without looking to someone to be responsible for his payment? who puts in vines and does not take the fruit of them? or who takes care of sheep without drinking of their milk?

If any man makes use of a tongue, let it not be more than two, or at the most three, and in turn; and let someone give the sense:

But someone will say, How do the dead come back? and with what sort of body do they come?
