These laws are,
I. Concerning trusts, Exo 22:7-13. If a man deliver goods, suppose to a carrier to be conveyed, or to a warehouse-keeper to be preserved, or cattle to a farmer to be fed, upon a valuable consideration, and if a special confidence be reposed in the person they are lodged with, in case these goods be stolen or lost, perish or be damaged, if it appear that it was not by any fault of the trustee, the owner must stand to the loss, otherwise he that has been false to this trust must be compelled to make satisfaction. The trustee must aver his innocence upon oath before the judges, if the case was such as afforded no other proof, and they were to determine the matter according as it appeared. This teaches us, 1. That we ought to be very careful of every thing we are entrusted with, as careful of it, though it be another's, as if it were our own. It is unjust and base, and that which all the world cries shame on, to betray a trust. 2. That there is such a general failing of truth and justice upon earth as gives too much occasion to suspect men's honesty whenever it is their interest to be dishonest. 3. That an oath for confirmation is an end of strife, Heb 6:16. It is called an oath for the Lord (Exo 22:11), because to him the appeal is made, not only as to a witness of truth, but as to an avenger of wrong and falsehood. Those that had offered injury to their neighbour by doing any unjust thing, yet, it might be hoped, had not so far debauched their consciences as to profane an oath of the Lord, and call the God of truth to be witness to a lie: perjury is a sin which natural conscience startles at as much as any other. The religion of an oath is very ancient, and a plain indication of the universal belief of a God, and a providence, and a judgment to come. 4. That magistracy is an ordinance of God, designed, among other intentions, to assist men both in discovering rights disputed and recovering rights denied; and great respect ought to be paid to the determination of the judges. 5. That there is no reason why a man should suffer for that which he could not help: masters should consider this, in dealing with their servants, and not rebuke that as a fault which was a mischance, and which they themselves, had they been in their servants' places, could not have prevented.
II. Concerning loans, Exo 22:14, Exo 22:15. If a man (suppose) lent his team to his neighbour, if the owner was with it, or was to receive profit for the loan of it, whatever harm befel the cattle the owner must stand to the loss of: but if the owner was so kind to the borrower as to lend it to him gratis, and put such a confidence in him as to trust it from under his own eye, then, if any harm happened, the borrower must make it good. Let us learn hence to be very careful not to abuse any thing that is lent us; it is not only unjust, but base and disingenuous, inasmuch as it is rendering evil for good; we should much rather choose to lose ourselves than that any should sustain loss by their kindness to us. Alas, master! for it was borrowed, Kg2 6:5.

An oath of the Lord be between them - So solemn and awful were all appeals to God considered in those ancient times, that it was taken for granted that the man was innocent who could by an oath appeal to the omniscient God that he had not put his hand to his neighbor's goods. Since oaths have become multiplied, and since they have been administered on the most trifling occasions, their solemnity is gone, and their importance little regarded. Should the oath ever reacquire its weight and importance, it must be when administered only in cases of peculiar delicacy and difficulty, and as sparingly as in the days of Moses.

Then shall an oath of the Lord be between them both,.... Either by the one, the keeper, for the satisfaction of the owner, or by them both; by the owner, that he delivered such and such cattle to the keeper; and by the keeper, that he was no ways concerned in the death, hurt, or carrying off of the same: and this is called "the oath of the Lord", not only because in this law required by him, but because sworn by him, or in his name, and made before him, in his presence, who is hereby appealed unto; and who is called upon to take vengeance on the person that takes the oath of perjury; and such an oath only is a lawful one, men are to swear only by the Lord. But this oath was not tendered to anyone:"if a man was suspected of an oath (i.e. of perjury) they might not give him his oath, neither the oath of the law, nor the oath from their words (the scribes), nor the oath of imposition (imposed by the wise wen); and even though he that brought the action would have it, they might not hearken unto him: if a man has swore falsely a rash oath, or an oath of testimony, or an oath concerning anything deposited, or a vain oath, lo, he is suspected of an oath, and so everyone that is rejected for witness on account of any transgression (w).''The oath to be taken by the keeper, and who indeed seems to be the only person that was to take one, was, "that he hath not put his hand unto his neighbour's goods"; so as either to kill or maim, or drive away, or suffer to be driven away, any of the cattle committed to his care, or that he had not disposed of them to his own use and profit:

and the owner of it shall accept thereof; of the oath, as the Targum of Jonathan and Jarchi, and so be satisfied, and give no further trouble, such an oath being for the confirmation of the thing, and to put an end to strife; or he shall take the ass, ox, or sheep, as it was, and be content; but then, though he might take the dead or maimed one, he could not take that which was driven or carried away, wherefore the first sense, is best:

and he shall not make it good; or pay for it to the owner what it was worth.

If fire break out, and catch in thorns--This refers to the common practice in the East of setting fire to the dry grass before the fall of the autumnal rains, which prevents the ravages of vermin, and is considered a good preparation of the ground for the next crop. The very parched state of the herbage and the long droughts of summer, make the kindling of a fire an operation often dangerous, and always requiring caution from its liability to spread rapidly.

stacks--or as it is rendered "shocks" (Jdg 15:5; Job 5:26), means simply a bundle of loose sheaves.
