'Someone's' in the Bible

"'As for the priest who presents someone's burnt offering, the hide of that burnt offering which he presented belongs to him.

"When someone's body has a boil on its skin and it heals,

When someone's prosperity increases, those who consume it also increase; so what does its owner gain, except that he gets to see it with his eyes?

If someone's work is burned up, he will suffer loss. He himself will be saved, but only as through fire.
