'Someone' in the Bible

" '{Whoever strikes someone} and he dies will surely be put to death.

" 'And {whoever kidnaps someone} and sells him, or he is found in his possession, he will surely be put to death.

Concerning every account of transgression--concerning an ox, concerning a donkey, concerning small livestock, concerning clothing, concerning all lost property--where [someone] says, "This belongs to me," the matter of the two of them will come to God; whomever God declares guilty will make double restitution to his neighbor.
