4 Thou shalt not see thy brother's ass or his ox fall down by the way, and hide thyself from them: thou shalt surely help him to lift them up again.
[AD 215] Clement of Alexandria on Deuteronomy 22:1-4
Scripture teaches us by means of natural fellowship to treat the object found as a trust and not to hold hatred of an enemy.

[AD 270] Gregory of Neocaesarea on Deuteronomy 22:1-4
So says Deuteronomy. But in Exodus, even if someone finds what belongs to his enemy, not just his brother, it says, “Turn and take them back to their owner’s house.”

[AD 542] Caesarius of Arles on Deuteronomy 22:1-4
You are commanded to pull out the ass or the ox which is lying in the mud. Do you then see a Christian like yourself, who was redeemed by the blood of Christ, lying in the sewer of drunkenness and wallowing in the mud of dissipation, and remain silent? Do you pass by and not stretch forth the hand of mercy? Do you merely shout at him or rebuke him or instill fright in him?
