'Owner' in the Bible

and this is the matter of the release: Every owner of a loan is to release his hand which he doth lift up against his neighbour, he doth not exact of his neighbour and of his brother, but hath proclaimed a release to Jehovah;

If the owner does not live near you or you do not know who the owner is, then you must corral the animal at your house and let it stay with you until the owner looks for it; then you must return it to him.
