Deuteronomy 22:1,2

Thy brother's Any man's, this being a duty of common justice and charity, which the law of nature taught even heathen. Hide thyself from them Dissemble, or pretend that thou dost not see them, or pass them by as if thou hadst not seen them. If thy brother be not nigh unto thee Which may make the duty more troublesome or chargeable. Or if thou know him not Which implies that, if they did know the owner, they should restore it. Bring it unto thy own house To be used like thy other cattle. Thou shalt restore it again The owner, as it may be presumed, paying the charges.
