Deuteronomy 22:1-2

New Revised Standard Version, Anglicised Catholic Edition

22 You shall not watch your neighbour’s ox or sheep straying away and ignore them; you shall take them back to their owner. ² If the owner does not reside near you or you do not know who the owner is, you shall bring it to your own house, and it shall remain with you until the owner claims it; then you shall return it.
