| Clarke's Commentary on the Bible Thou mayest not hide thyself - Thou shalt not keep out of the way of affording help, nor pretend thou didst not see occasion to render thy neighbor any service. The priest and the Levite, when they saw the wounded man, passed by on the other side of the way, Luke 10:31, Luke 10:32. This was a notorious breach of the merciful law mentioned above.
Gill's Exposition of the Entire BibleIn like manner shall thou do with his ass,.... As with his ox or sheep when astray, and found, keep it until it is owned, and then restore it; this is expressly mentioned in Exodus 23:4. and so shalt thou do with his raiment; if that is lost and found, it must be restored to the owner, he describing it; a garment is particularly mentioned, it is said (a), because in every garment there is a mark or sign by which the owners can inquire about it; for it is made by the hands of men, and does not come from anything common: and with all lost things of thy brother's, which he hath lost, and thou hast found, shalt thou do likewise: this comprehends everything that is lost, that is properly so; it is asked (b);"what is a lost thing? if a man finds an ox or a cow feeding in the way, this is not a lost thing; an ass whose instruments are inverted, and a cow running among the vineyards, this is a lost thing:" thou mayest not hide thyself: from seeing it and taking care of it, in order to restore it to the right owner; or dissemble a sight of it, and pretend he never saw it, and so entirely neglect it. In some instances the Jews allow they were not obliged to take any notice or care of it, as,"if a man find a cow in a cow house (which is not shut), he is not obliged (to take care of it); if in a public place, he is obliged; if it is in a burying ground he may not defile himself for it (c).''

Geneva Study BibleIn like manner shalt thou do with his {c} ass; and so shalt thou do with his raiment; and with all lost thing of thy brother's, which he hath lost, and thou hast found, shalt thou do likewise: thou mayest not hide thyself. (c) You are bound to do much more for your neighbour.
Wesley's Notes 22:3 Hide thyself - Dissemble that thou hast found it. Or, hide it, that is, conceal the thing lost.
Matthew Henry's Concise Commentary22:1-4 If we duly regard the golden rule of doing to others as we would they should do unto us, many particular precepts might be omitted. We can have no property in any thing that we find. Religion teaches us to be neighbourly, and to be ready to do all good offices to all men. We know not how soon we may have occasion for help.
Matthew Henry's Whole Bible CommentaryChapter 22 The laws of this chapter provide, I. For the preservation of charity and good neighbourship, in the care of strayed or fallen cattle (v. 1-4). II. For the preservation of order and distinction, that men and women should not wear one another's clothes (v. 5), and that other needless mixtures should be avoided (v. 9-11). III. For the preservation of birds (v. 6, 7). IV. Of life (v. 8). V. Of the commandments (v. 12). VI. Of the reputation of a wife abused, if she were innocent (v. 13-19), but for her punishment if guilty (v. 20, 21). VII. For the preservation of the chastity of wives (v. 22). Virgins betrothed (v. 23-27), or not betrothed (v. 28, 29). And, lastly, against incest (v. 30). Verses 1-4 The kindness that was commanded to be shown in reference to an enemy (Ex. 23:4, etc.) is here required to be much more done for a neighbour, though he were not an Israelite, for the law is consonant to natural equity. 1. That strayed cattle should be brought back, either to the owner or to the pasture out of which they had gone astray, v. 1, 2. This must be done in pity to the very cattle, which, while they wandered, were exposed; and in civility and respect to the owner, nay, and in justice to him, for it was doing as we would be done by, which is one of the fundamental laws of equity. Note, Religion teaches us to be neighbourly, and to be ready to do all good offices, as we have opportunity, to all men. In doing this, (1.) They must not mind trouble, but, if they knew who the owner was, must take it back themselves; for, if they should only send notice to the owner to come and look after it himself, some mischief might befal it ere he could reach it. (2.) They must not mind expense, but, if they knew not who the owner was, must take it home and feed it till the owner was found. If such care must be taken of a neighbour's ox or ass going astray, much more of himself going astray from God and his duty; we should do our utmost to convert him (Jam. 5:19), and restore him, considering ourselves, Gal. 6:1. 2. That lost goods should be brought to the owner, v. 3. The Jews say, "He that found the lost goods was to give public notice of them by the common crier three or four times," according to the usage with us; if the owner could not be found, he that found the goods might convert them to his own use; but (say some learned writers in this case) he would do very well to give the value of the goods to the poor. 3. That cattle in distress should be helped, v. 4. This must be done both in compassion to the brute-creatures (for a merciful man regardeth the life of a beast, though it be not his own) and in love and friendship to our neighbour, not knowing how soon we may have occasion for his help. If one member may say to another, "I have at present no need of thee," it cannot say, "I never shall." |
