Deuteronomy 22:1
Thou shalt not see thy brother’s ox or his sheep go astray, and hide thyself from them: thou shalt in any case bring them again unto thy brother. Thou shalt not see thy brother’s ox or his sheep go astray, and hide thyself from them: thou shalt in any case bring them again unto thy brother.
The law forbids seeing a brother's ox or his sheep going astray and hiding oneself from them, and commands in any case bringing them back again to the brother, so that a neighbor's lost or wandering animal must not be ignored but must be helped to recovery. When such livestock is seen in one's own field, that duty calls for prompt action, either telling the neighbor at once or driving the animals out.
While stray property, including ox or sheep, must thus be returned to its owner, an escaped servant must not be returned to a master but must be protected. The mercy required toward straying animals extends to persons in distress, so that passing by a suffering man as the priest and Levite did is a breach of the same duty to show mercy. Such practical help in small matters is true neighborliness, and by it the neighbor may be won.
