(4) Thine enemy's ox.--The general duty of stopping stray animals and restoring them to friendly owners, expressly taught in Deuteronomy 22:1-3, is here implied as if admitted on all hands. The legislator extends this duty to cases where the owner is our personal enemy. It was not generally recognised in antiquity that men's enemies had any claims upon them. Cicero, indeed, says--"Sunt autem quaedam officia etiam adversus eos servanda, a quibus injuriam aceeperis" (De Off. i. 11); but he stops short of enjoining active benevolence. Here and in Exodus 23:5 we have a sort of anticipation of Christianity--active kindness to an enemy being required, even when it costs us some trouble. The principle of friendliness is involved--the germ which in Christianity blossoms out into the precept, "Love your enemies."

Verse 4. - Thine enemy's ox. A private enemy is here spoken of, not a public one, as in Deuteronomy 23:6. It is remarkable that the law should have so far anticipated Christianity as to have laid it down that men have duties of friendliness even towards their enemies, and are bound under certain circumstances to render them a service. "Hate thine enemies" (Matthew 5:43) was no injunction of the Mosaic taw, but a conclusion which Rabbinical teachers unwarrantably drew from it. Christianity, however, goes far beyond Mosaism in laying down the broad precept - "Love your enemies."

23:1-9 In the law of Moses are very plain marks of sound moral feeling, and of true political wisdom. Every thing in it is suited to the desired and avowed object, the worship of one only God, and the separation of Israel from the pagan world. Neither parties, friends, witnesses, nor common opinions, must move us to lessen great faults, to aggravate small ones, excuse offenders, accuse the innocent, or misrepresent any thing.If thou meet thine enemy's ox or his ass going astray,.... Or any other beast, as the Samaritan version adds; for these are only mentioned for instances, as being more common, and creatures subject to go astray; now when such as these are met going astray, so as to be in danger of being lost to the owner, though he is an enemy; or as the Targum of Jonathan,"whom thou hatest because of a sin, which thou alone knowest in him;''yet this was not so far to prejudice the finder of his beasts against him, as to be careless about them, to suffer them to go on without acquainting him with them, or returning them to him, as follows:

thou shalt surely bring it back to him again; whether it be an ox, or an ass, or any other beast, the law is very strong and binding upon the finder to return it to his neighbour, though an enemy, and bring it either to his field or to his farm.
