Deuteronomy 22:2

And if thy brother be not nigh unto thee, or if thou know him not, then thou shalt bring it unto thine own house, and it shall be with thee until thy brother seek after it, and thou shalt restore it to him again.

If your brother isn't near to you, or if you don't know him, then you shall bring it home to your house, and it shall be with you until your brother seek after it, and you shall restore it to him.

And if thy brother be not nigh unto thee, or if thou know him not, then thou shalt bring it home to thy house, and it shall be with thee until thy brother seek after it, and thou shalt restore it to him.

and if thy brother `is' not near unto thee, and thou hast not known him, then thou hast removed it unto the midst of thy house, and it hath been with thee till thy brother seek it, and thou hast given it back to him;

If your brother does not live near you, or if you do not know who he is, you are to take the animal home to remain with you until your brother comes seeking it; then you can return it to him.
