Deuteronomy 22:1-3

Thou shalt not see thy brother’s ox or his sheep go astray, and hide thyself from them: thou shalt surely bring them again unto thy brother. 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 so shalt thou do with his ass; and so shalt thou do with his garment; and so shalt thou do with every lost thing of thy brother’s, which he hath lost, and thou hast found: thou mayest not hide thyself.
